I have LTE turned on in my area and when I use my wireless tether for root users I get awesome speeds between 2-3MBps but after about 150-200MB downloaded those speeds immediately drop off to just 10-20k or so. Now I rarely go over the 5GB soft cap and even when I do it's only by a few hundred MBs. Is there some sort of throttling going on and any way to stop it?
It has been discussed actually (and with that application), but anyways, at least you tried
Assuming your speeds are bad due to one application isnt exactly a very good test (more so since you did not say what version of the application you are running since that could matter). If you want to be certain, try internet connection mode via usb and download a test file from a location around you, such as from one of these data centers http://www.linode.com/speedtest/ and watch the speed. Doing that, you can eliminate plenty of variables, like the wifi connection on either end acting up for whatever reason and the application.
If it stays constant, then it's the app. If it doesn't, well that's not a 100% indication either. LTE is unstable speeds will fluctuate. If you're only testing from one location, that's not a very good conclusion either.
Whenever you have a problem, try to go through the total process of elimination only focusing on one variable at a time and try to keep everything else the same. Most likely it's you or the current setup on your phone or the application, not verizon. How do I know this? Because many have downloaded way more than you have and haven't been throttled (just from people I know locally with an LTE enabled phone).
Exusting all possible outcomes is a much better conclusion than wildly guessing you are being throttled though.
Another way you can test directly on your phone:
1) open up the terminal
2) type the 3 lines below: (downloads a file, gets the time it took and then removes it after)
cd /mnt/sdcard
time wget http://207.192.68.6/100MB-newark.bin
rm 100MB-newark.bin
*if the above doesn't work, then you need busybox, but nearly every rom/kernel has it that's not stock, so you should by default, have it. If not, search in the market for busybox installer. The reason you see an ip there is wget doesnt play well with hostnames on the android due to the way it resolves domains and busybox generally being statically linked. If you want to try another url, you have to get the ip like above (you can do that by pinging the hostname on your phone).
3)Note "real" the time it took in seconds and divide 100 by that to get Megabytes per second (MBps not Mbps) or by 102400 to get Kilobytes per second (I suppose you could get Megabits, but that's a pretty pointless measurement other than making your connection look fast compared to saying bytes, since your files all appear in bytes and browser downloads show in bytes). If you really care about mbps, multiple what you did above already by 8.
4) when it finishes you have an answer totally on your phone alone.

I believe there is a problem with the "Wireless Tether" app. I don't think it plays well with the 4G, this could be a reason for it. Have you tried used the "Mobile Hotspot" app, that comes with the phone? Do you get the same results?
I have also used the stock mobile hotspot app as well as tether via usb and get the same result. For clarification... I am downloading large files (500mb or larger) from a work server so I know that it's a problem on my phone end and not a problem on the server end. I can be on my home computer and download the files and never drop below 5MBps download the whole time... usually never drop below 10MBps to be honest.
Android police says that the way wireless tether works.. there is no way to tell if you're tethering or not without digging deep into packets.. deep enough that it would be invasion of privacy

That's all good and well but there is definitely something going on here. I've run the same test same file all 3 ways once every 4 hours since my first post and at about 150-200mb downloaded my speeds drop to almost non existent and the same goes for files downloaded from Microsoft and Google among others. Downloading the same file from my home internet does not see this slow down at all. I've even tried letting it run for over an hour like that to see if it was something temporary. It seems to stay throttled down till I've let the phone sit for a few hours without using any data then kicks back up to normal speeds until I restart another large download.
Is there any way to do a more controlled experiment to see if I'm crazy, unique or what?

yeah...backup your current rom, flash and restore your phone back to near stock (still rooted) and try without any meddling (custom stuff) http://www.multiupload.com/26WG1UZCXR http://forum.xda-developers.com/showthread.php?t=1009423
you also never mentioned what android version and rom you are currently using. if it's anything other than froyo, that could be your problem since nothing else is anywhere as stable (by stable, i dont mean "oh it works" i mean as in tested throughly and was put out for non testing release).
Though the above suggestions stated above likely are the culprit, and will help you...there is also a chance that you are indeed being throttled occasionally. Infact, I'm sure we all have been. Verizon has several manned data centers throughout the state who monitor all the traffic happening, and can, and will, activately manupulate the speeds, thoroughput, etc depending on how conjestion things are. And yes, they can even pinpoint it on an individual level...though they rarely do that, tending to focus on what's happening on a more macro level.
I actually wasn't even aware of this until recently, but some guy who worked at Verizon who was also in school for that sort of thing let it slip when we started chatting for a second, to which he received a scathing look from the ***** manager, so that ended the conversation.
I was running DasBAMF 1.6.3 and I did return to stock without root this morning to try it out that way as well and I'm still seeing the same results.

Find someone else with a 4g device and have them download next to you at the same time. Only other option I can think of doing.
I'll try that.
Update:
I got with a few friends and tried a few different things. 3 people with Thunderbolts and 2 with Droid Charge. 2 in Seattle and 3 in Spokane. The Thunderbolts rooted and running DasBAMF 1.6.3 and the Charges fully stock. We tried the download using 3 methods for the TBolt's (wireless tether for root, mobile hotspot and USB tether) and the Charges used the mobile hotspot.
We all downloaded the same files. A 512mb video file, 400mb zipped picture file and a 300mb document file.
My Seattle friends who have had the "official" 4G LTE launch had no issues downloading at all... 1 TBolt and 1 Charge. Download went smoothly and never throttled down at all.
All 3 of us here in Spokane saw the same throttling going on. Could this be more an effect of LTE not being "officially" deployed in Spokane yet? It's not supposed to be officially launched till June 19th but we've been able to access it for several weeks now.

I would say that's a possibility. I get around 130 kbit/sec down, and LTE was officially launched here in december but only at our airport. I've been checking for nearly two weeks now and it's stayed the same. the upload is normal, was 3.5mbit/sec today.
This is all good to know. I'll be in Seattle next week for work. Can't wait to have 4G for a week
So I followed the instructions in the v6 SuperCharger script thread and the phone is wicked fast now, virtually no lag whatsoever. But I have what appears to be a battery drain issue. Spare Parts and SystemPanel let me zero in on a process called "zygote" which was consuming 30% of the CPU even when the screen was off. I may try disabling the script to see what happens but I'd hate to go back to the stock laggy experience.
Does anyone know what zygote does or is for and why it would keep running continuously? Are the new memory values causing the phone to keep shifting around apps/processes to maintain the minimum free memory and this is using up CPU and therefore battery?
Eric
Which areas on the phone were you noticing considerable lag?
Did you also figure out what the process was and why it was taking up so many cycles?

Are you asking me? The process is called "zygote" in SystemPanel. Under Spare Parts, Android System was shown as keeping the phone awake.
The original lag I was experiencing was within various apps and also ADW Launcher flipping between homescreens.
Eric
I was intrigued and googled it. The best answer I found without too much digging was here:
http://groups.google.com/group/android-discuss/browse_thread/thread/fa8a9e3f3b891b0d/44b3bb43d0aa783a
But by that explanation it doesnt seem like zygote should be using that much cpu. Perhaps this script changes its behavior?
Still surprised people do not have red flags for concern in regards to having to use this app in the first place. People are having to use an app designed for low memory devices (256mb) on a device with 512mb. gTablet has 512mb, Tegra 2, Froyo as well, but does NOT have these problems and performs much better (never thought I would say that, but the gtablet DOES perform MUCH better).
That said, if the mystery of the low ram issue, audio pops and random reboots are fixed in an update- the DX2 will be great (IMO). Had the DX2 for two weeks and wanted to keep it, but the issues mentioned were not worth messing with. Having the similar software and hardware on the gTablet gave me a source for comparing and realizing something is wrong with the DX2's firmware.
Not to hijack, but when you get to this part in the Tutorial, which setting should one choose for the x2?
"Touch the screen and tap the number 6, Balanced 3, the best choice for GT540, and hit ENTER .... The script will work .... after finished, touch the screen again and tap the number 16"

You're an idiot.
I've told you a few times already that the script fixes badly configured memory management no matter what the device.
The minfrees is a secondary to the primary function - fixing OOM groupings and priorities for optimal performance.
Is an app like AKMO or AMM only good for 256 mb devices?
No, they aren't. But all they do is change minfree values.
So don't be so stupid.
And for those that think it's causing battery drain, unsupercharge.
You will still have battery drain and the phone will be slower.

You appear to be a rude individual who disgraces Led Zep and showed be forced to change your icon to Vanilla Ice
The DX2 should NOT require to be managed for low ram. gTablet has none of these issues and besides some telephony tasks, has the same hardware and software setup as the DX2- none of the issues and no need to have to manage low operational ram. Seems the DX2 does not truly have 512mb of FUNCTIONAL ram, hence the need to run non standard scripts. For folks that do not root, they are SCREWED due to pi55 poor firmware by Motorola.
Start being nicer to people and you can keep your Led Zep icon with honor/honour.

I tend to agree with you on this. Having dealt with hardware for 25+ years, rarely does the hardware come optimized to a truly great point. Some are definitely worse than others, but there can still be improvements.
Expecting a perfectly optimized piece of hardware/software from any company seems bit foolish. Fortunately the community that uses the hardware are generally the best at getting it to it's best state, regardless of what those who like to drink the koolaid might say.
In any case, I ran this on my X2 and everything had been tip-top since. I have not seen this Zygote issue and I used option 9.

Not seeing/tasting the koolaid here. Very simple point that out of box, the DX2 has to be managed like a 256mb ram device. I have been around a tad too and have my undergrad in computer electronics (so far back, we still used Tandy's to program eeproms then) so have a teeny bit of subject matter appreciation.
The points were never about the script, but the device itself. Out of box, the device operates with low ram- just like the Droid 1 (which I also owned). Back then, no problem, since 2.1 and lower only really used 256mb ram and the Droid 1 was (IMO) ten times better than the G1 that I also bought at launch.
For as long as there have been computers, people have been tweaking them.
Tell me, does each windows computer sold have a different memory configuration depending on ram?
No, its managed the same across the board.
Same thing with android.
I've been tweaking them since I had a pentium 90..ya... 90mhz with windows95.
You got rid of it and still troll forums as your new hobby.
No, you didn't drink the koolaid.
You tried V6 with low ram values, ignored my suggested megamemory settings, returned the phone, and troll and whine every chance you get about it.
So stop being an ignorant suck and enjoy your new whatever...
Oh yeah... I can be rude... big deal.
Just like you can be ignorant.
I just have a low tolerance to intentional ignorance.
You still spew stuff about 256mb device settings despite the fact that the script has megamemory device settings while the main feature is fixing the notoriously bad memory configuration of gingerbread on ALL devices.
If you can't grasp that, you're stupid too.

Ive had my gs3 for a week now. Moved from my htc tp2.
Firstly the signal quality is worse. Sat in my normal place in the house and unable to hear people. Have to go to the window.....4 year newer upgrade should be a total upgrade.
Secondly my partner has a galaxy S. We've been playing uno across bt. If you haven't played it one person hosts and the other joins. My partner was contantly the host as her phone could load in and out of the multiplayer in 1/2 the time... galaxy s better then gs3...! Grrrr
The question or oddity i have is memory.
Out the box i was getting about 500 mb usage. Few task managers/startup kills downloaded and tried. Gained about 50 mb. Used fmr memory and got down to about 350 mb.
Then started trying a few apps... wifi finders. File managers. Clocks etc. Noticed memory usage up to 550 mb. Looked at a few task managers again. Killed a few things. Used fmr again but unable to get anywere near 450mb. The task manager dont show any of the new apps. Uninstalling the new apps got my memory usage back down. But why..... if the task managers ( tried the top 5-6 and inbuilt for comparison) show no additional apps in memory where is it going.
This may-be my lack of understanding of how android works. Or a failure on the compatibility of the task managers and gs3. Or maybe im using the workings of a pc and incorrctly comparing.
Can anyone explain....
Sorry about any typo's. Still getting my head round this keyboard....
Need an android qwerty in the uk... this phone will be ebayed...my tp2 died so HAD to get a new phone. Gs3.

Not bad.. screen is lush... size too long (only time i had to go 2 handed with my tp2 was when using the phyical qwerty, contantly using 2 hands with this size screen. Nearly droped several times juggeling and i have man hands). Home button should be touch not phyiscal.

Why do you worry about memory usage if it doesnt do any harm? you can start worrying about it if your the gs3 starts to run slowly etc.
I think you are worrying about task managers and memory usage because you got used to wm This is android and gs3 is beast of a phone, no need to worry too much about closing apps or memory usage.

Cache is "eating" up your RAM. Take a look at this page: http://www.linuxatemyram.com/
All operating systems do it, some just don't show it that prominent because it confuses the heck out of new users.
Using Task managers actually slows your phone down since it has to load data from the SSD which is always orders of magnitude slower than RAM.
However Samsung - and if your phone is carrier-branded, the carriers too - have added a lot of crap- and bloatware to he devices. If you're rooted, you can easily freeze or remove it which should give you 100ish MB of additional RAM. It's the same as with all devices that are sold today,
I'm wondering when they will start shipping ovens with a 30day Trial of PizzaBaker Pro.

Try another modem. That often makes huge differences. However, as usual, modems with better signal drain more battery since they send with a higher signal strength.

I don't know that game and altough I've both phones (S1 and S3) sitting in front of me I'm not particularly inclined to try it out now
However there could be several reasons to this behaviour, including e.g. the game trying to load higher texture resolutions for your far larger and higher-resolution screen, the app having issues with your particular phone,....
Is your partner's S1 on Android 2.x or 4.0? On CM7 / CM9 or another ROM? S1+ CM9 is very fast and it's snapiness not far behind the S3 without CM9.

Dont get me wrong love the phone. This was a list of first week oddities. The things i love about this do outway.
I would upgrade to a high spec qwerty slide in a heart beat. But the spec would need to compaire to this phone. Screen quality is 5*. Touch sensitivity again lush. Sound... and many more great features.

Modem..... didnt even consider it.. many thanks.
Ruchira88. You may be spot on there. Allways had to keep one eye on tm with wm6.5. Have noiced an occational lag but i was running alot.
Keyboard..... just not a huge fan of on screen keyboards.. i know many people prefer them but still prefer a qwety slide. I find it quicker and more accurate for me.
My point about the home button. I find i have to shift my hand to add presure. May be the way im holding it. First week with a phone this big. Also have sgs3 flip case. Nice but also could be an added interference

In the past I've always had these issues over time, but I always contributed it mainly to running custom ROM's. Well, when I got my M8, it ran so well I decided to leave it stock. Well it's finally starting to hit a wall and it's more of a frustration than a joy to use. Swype is borderline impossible to use since it lags so bad, freezes are infrequent but occur, etc etc.
So my question is, what are the most likely contributors? Apps that run in the background? Too many apps? Too much space used? I can't think of much else, since, like I said, it's still fully stock. Or is this just what I have to expect from a phone?
Do you clear the cache in your app settings. If you game a lot than I would definitely start with the game apps first.

Android 5.0.1 is pretty lag free in my opinion

I kept my phone stock for quite some time because I felt I didn't need to change anything, until last week because I was tired of radio issues. Bottom line, ATT sucks at getting updates out, so if your running stock, your firmware is like three updates back. I see a massive improvements in speed and battery with 3.28.1540.5. If you know how, I would S-OFF and upgrade firmware to that and flash the debloated custom stock Rom that comes with root and SU. There are straight forward instructions in the att m8 development thread.

I might look into this. What I don't get though.. I can understand if new updates are quicker. That makes sense. What doesn't, is how ridiculously poor my phone runs compared to the first few months I had it. It's been like this for every phone I've had. I don't game, I don't have all that many apps. In my running app list, the only self installed things there are Facebook and Swype. I have plenty of extra storage internal and on my SD. So what is it that causes such poor performance over time? I'll definitely have to check out the newer roms and finally s-off.. but I've done plenty of custom roms before with other phones and the same thing always happens, things run fine for a bit and then slowly go to crap.

Its hard to say what is causing your issue, and aside from saying Swype is lagging (might be an issue with that app itself) and the phone "doesn't run so great anymore" you really haven't provided any specifics of what the problem is. You also haven't indicated if you tried to clear cached as jball suggested, and if so, if it helped at all.
Might be some runaway (poorly coded) AT&T bloat apps. But in general, apps running in the background will not slow the system down much. There are various apps to track battery and memory usage, so you might try one of those, to determine if any particular apps are the culprit.
I can't say I've seen any lag on my M8, but I switch ROMs fairly occasionally, and keep it updated to current Android builds (thanks to s-off). Clearing up your data partition alone might help (but might now, on the other hand) so you might also consider backing up any personal data and doing a factory reset. Wiping the slate clean might solve your issue.
Ok.. well a lot info there but one step at a time. I realized my phone is Sunday unusable with Wi-Fi turned on.. which is quite interesting and I'm pretty lost on this one. With Wi-Fi on, it's like my entire phone stops, not just the actual internet speeds. Apps like Facebook take ten seconds just to load, and then the actual content takes sometimes 15 seconds to load or maybe not even at all. Also, keep in mind, my actual internet speeds are fine, and even test perfectly fine on my phone.
As soon as I turn off Wi-Fi, it seems everything on my phone I'd dramatically quicker and everything loads near immediate. I've tried restarting my phone, cycling airplane mode, not really sure what else to do.

Does it happen anywhere you use WiFi? If so maybe try fully wiping and flashing the firmware, or just bust out the ruu to make it easier, can't hurt to try it should help tho
Did you even try to wipe cache, as has been suggested twice previously?
Otherwise, if no major system changes, and the phone has just been running worse and worse, a factory reset may help; as I would have to think it may be 3rd party apps that are to blame. Backup your personal data, factory reset, and just start to install a minimum of apps, and see how it runs.
If still no improvement, the above comment to try to RUU is not a bad idea, either. RUU provides a fully "blank slate" and may solve your issue.
My Nexus 9 is running slow most of the times and it takes while to I switch between apps or open an app most of the times...what is the fix for that? I have been trying clearing the dalvick cache several times but no help...and I really don't have lots of apps. Thanks for your help in advance.

Try tapping on 'Memory used by apps' on that memory settings screen, should let you know what the culprit is

Firstly, you need to face the fact that 2GB was a bad decision by Google for this tablet. There is nothing that we can ever do about that. :crying:
If you want to stay on stock, Chrome is the main culprit in consuming Ram. Switching to Habit Browser makes things better as well as changing your DPI to 288. Do a search on XDA regarding this. Whilst it improved things, it was still not enough for me.
I snapped a week ago and have now rooted and flashed CM13 and stuck with Habit. I've been using a few days now, and for the first time, I can keep my 3 Fantasy Premier League Tabs open, (they are huge,) without constant refreshes, redraws and lag. :victory: Right now, I feel for the first time, I'm getting what I paid for and the Nexus Experience. The only bug so far, is that always listening doesn't work.
If you've just bought this tablet, I'd consider returning it if you are not prepared to root. The performance will never be acceptable on stock.

Clearing dalvik cache will do precisely ONE thing and ONLY one thing; make it take a long time to boot next time as it regenerates it.
Ignore the amount of available memory. People who are concerned about the amount of free memory are trying to apply bad mswindows knowledge to Android. Totally different and no comparison. UNUSED MEMORY IS WASTED MEMORY!!!
So here is how memory management works in Android; it *preloads* everything that it thinks you are most likely to actually use, so that when you DO use it, it is more likely already loaded and starts up very quickly. If you are switching to something that is NOT already loaded, then it just needs to dump lower priority programs out of memory, which basically only takes a few nanoseconds (billionths of a second). So that is NOT it.
If your device is acting slowly, then you need to figure out what the actual cause is. Trace the CPU utilization with something like the "top" command (the one with busybox is a lot nicer than the one that comes with Android) while you are experiencing slowdown. You can also look to see if there is excessive I/O happening (i.e. read/write to the internal storage), and of course, some software will require a network exchange before it will start up -- nothing you can do about network lags.

I have done it several times. As I said, I really have not so many apps and just the very common google apps are installed.

Thanks for your reply. Yeah, most of the times, the slow down happens while I am in chrome and browsing..it actually is not snappy at all in internet browsing...however, I remember it was back in the days that I had bought it.
No, I have this Nexus 9 since last May I think, but have not yet found the time to root it and flash a custom kernel and rom . Anywyas, I have done it previously for my other devices, so not that much rookie in it. Probably will give it a try,

Thanks for your kind reply and explanation.
I think that is exactly the problem as even sometimes switching between the apps that I have just opened is also so slow and the nexus lags badly....Yes, I am aware of the network lags, but the problem I was talking about does not have anything to do with it...I will try the command you said, but can I run it on stock rom? I have not yet rooted my nexus nor flashed a custom rom.
Thanks

You can do some investigation by watching the processes and seeing which are taking the CPU and memory on stock. The problem is, when you find out, there isn't much you can do about it.

Its quicker and easier to just install a custom rom where this type of work has already been done for you. :victory:
Lately, I've discovered that loading Chrome immediately raises my CPU temp by 30+ degrees. Sometimes that's enough to make things run really slow
Yeah, I agree...I will try to fimd sometime amd go over flashing a custom rom. ??
Yes! I habe noticed that these slow downs mostly happen when I am browsing in Chrome...
Web browsers are DEFINITELY a source of slowdowns.
The problem, more often than not, is actually *javascript* that is written by MORONS. Even on a desktop machine, you can watch the web browser for CPU and RAM utilization, and it just grows and grows and grows until you finally kill the process and start a new one.
What this may come down to is actually quite simple; the CPU in the Nexus 9 is actually more suitable for use as a stovetop than an actual CPU. These things get way too hot way too fast. If you beat on them with a web browser, they'll get hot and throttle down to low/verylow frequency, which will make them generally unresponsive. So if that is what is happening to you, there really end up being a few options to deal with it;
1) disable javascript in the browser,
2) don't use the browser,
3) improve the ability to disperse heat from the CPU.
For #3, you may note that when it gets hot, it is pretty localized to the corner of the device up near the power button. An easy solution to distribute heat better might be something simple, like adding a layer of copper foil to the inside of the back cover. The thicker the copper foil the better. Copper is very good at conducting heat, so this would spread the heat around over the entire area covered by that foil. http://www.ebay.com/itm/Copper-Foil...nductive-Adhesive-Ship-from-USA-/162018486132
I also found chrome was slow starting up, switching tabs etc. Found that logging out of my Google account in chrome improved this. Seems that synching tabs etc triggers the pause. This might be an acceptable workaround for some but I appreciate it isn't a great fix if you want to use that feature. Actually I'm not bothered as I think Google know too much anyway. �� But the underlying problem is this tablet... I don't have this problem on my phone.

Yeah, they do get hot...and the browser is the problem, I agree...however, I think they are not the main reason...there is something wrong with low memory or maybe some apps...

I don't agree with that.
We use our N9's *all of the time*, and there is never any perceptible slowdown. Possibly with the exception of straining them with web browsers, but web browsers are... poopy... on EVERY platform and device, so that doesn't really stand out. Typically just minimize the use of web browsers and all is well.
Web browsers were good in 1996 when they were simple things to display an html website. Since then, they've added all kinds of useless crap to them that bloat them out, hog up tons of memory, and just generally make them into a useless waste of space.

Update:
I think I have kind of find the problem of low speed of my Nexus 9...I uninstalled an app that was for weather prediction and from that time on my Nexus 9 is very fast and responsive...No problem so far. I also uninstalled some other apps alogaide that which I was never using them,so I am not sure if the weather app was exactly the reason of the slow downs...but the other apps where just some games or some simple apps....well, I hope this information helps! Let me know your idea. Thanks everyone
