Slow transfer speed - Xperia Z2 Q&A, Help & Troubleshooting

I have currently left my Xperia Z2 connected to my laptop for almost 5 hours to transfer 18GB of Music and it still has about 25% left using the Sony Bridge for Mac program.
My iPhone completed this same transfer in a 40minutes.........
Is anyone else suffering from painfully slow transfer speeds?

Hmmm seems usual
I dont have this issue because i use adb to transfer files
The problem is the sony pc program and the method of conecton to the pc
Media transfer mode is slow, usualy 3mb per hour which means 6hrs for 18gb
Sony bridge can also be slow , 5mb meaning around 4 hrs
Try installing and using adb, adb usualy is around 15mb/s for me
Adb push /folder to push /where on the device

Wifi Lan Maximum Speed?

Hi guys,
I've got a Netgear wifi n router and a Netgear usb wifi n connected to my pc, and I'm using my gs3 as an ftp server to transfer files to and from my pc.
The problem is that I can get a max upload speed to and from my pc of 2.7mb a second. I should be getting better results as the router and wifi a stated as 300mb connection.
Anyone can give me some information regarding?
Thanks
Inviato dal mio GT-I9300
Same here, Im getting speeds of 2mbps and less with phone, while my laptop connected to same AP is giving 8 to 9mbps.
I even tryed disabling power saver mode but still no luck.
And both laptop and mobile were tested with same signal strength.
WiFi is kernel so you have the option of trying different kernels .

The speed I get when using a web based speedtester using my 60mb internet connection are:
2.4ghz:
connect at 65mb with router set to 300mb around 30mb transfer rate
connect at 72mb with router set to 145mb around 30mb transfer rate
5ghz:
connect at 150mb with router set to 300mb or 145mb around 62mb transffer rate
Not tried much else but if I were to run a local transfer I should see at least what I get using 5ghz wifi via internet tester.
I dont think your problem is hardware related. It could be a few things. So you would need to troubleshoot. Some ideas:
Ftp daemon using a lot of overhead can cause slowness, try a different daemon
Filesystem write and read speed, run some benchmarks to see
Kernel problem or sysctl variables, tcp send or recieve buffer for example. Sysctl -a in a terminal on your phone and see.
The key thing here though is that if I were to connect at 2.4ghz I would see around 3mb per second transfer rates.
Hope that helps.

I have a 150mbps 2.4ghz N router, giving me 2mbps speeds using ES file explorer, when its connected at 65mbps,
But i dont understand is why is it connecting at 65mbps in the first place,
and even after connecting at 65mbps giving such low transfer speeds,where as it should be giving 5-6mbps ideally or at-least a 4.
I have tryed it on Siyah and Perseus kernels with no/less difference in results,
Im trying to copy files on Internal SDcard which has transfer speeds of Read 53.4MBps and Write 22.16MBps
Will try different Ftp apps and see whether it makes any difference.

[Q] Remote HDD access

Hi,
I have a HTC Sensation XL running ICS, the device is not rooted. Does anyone know of any apps that I can use to remotely access a hard disc attached to my home router?
What I want to achieve is kind of my own cloud storage system, I have seen these networked hard drives that attach directly to your broadband router rather than being inside a P.C and then computers on the home network can access this hard drive via the router, kind of like a central storage area for every one in the household. Well I want to set up the same thing but with the added bonus of being able to access the HDD when I am out of the house as well, via my phone or android tablet. I spend a lot of time in the country on my own and fill my devices with music and films etc and basically I want to access my entire library of media remotely. I have tried drop box, sugar sync, Skydrive etc but they do not provide any where near enough storage space for my needs, at least not for free and if I can achieve the above I will not be limited by the storage capacity of the device.
I currently use Pocketcloud to access files on my PC when I am away from home and this is fine for when the computer is turned on but when its not obviously I cant access anything, my theory is that a HDD connected directly to my router would be accessible 24 hours day as it should be independent of my PC, the question is how to actually set this up.
I have tried using ES File explorer to detect my home network but it wont for some reason, I was hoping that if I got it to find my network it might allow me to do the above however I could be wrong so any advice that people could give regarding this would be great.
Thanks
Ben

[Q] Transfer Large Files From PC To Device

sup,
i wanted this device as a media tablet, i currently use plex on ipad to watch media which reqs having a computer on to stream it which isnt ideal. I tried usb and was so slow and then i tried the xperia connect thing which transfer ed one hd movie (7.64gb) in 10mins+ thats far too slow to be useful.
does anyone know of a way to transfer much faster than that, using wifi ideally since my router has 600+ on the 5ghz band?
apps: AirDroid, TotalCommander (has FTP, SFTP, SMB plugins) and a bunch more.

Download the PC client on your Web browser.
Be aware though. The XZ2 is restricted on its wi-fi download speeds.

Ive actually tried superbeam. It's very buggy and frequently drops connect no matter what I try.
Do you mean with the setting "wifi optimization"? I've unchecked that and get somewhere in the region of 460mbps from the tablet and z2 phone on 5ghz. It seems really odd to me that transfers are so slow, even via USB. It's a brand new device, they should have this crap sorted by now. It seems transfer rates haven't improved at all since android's conception.

Wifi will always suck for large files. It's never going to actually run at the speed it says it can do. Copying to a MicroSD directly using the pc and then putting the MicroSD into the tablet will always be quickest. Don't forget to change the disk policy in Windows to performance or it won't be the best speed.

Transfering data to a phone via SSH or Samba slow and often fails

I've fought and fought with transferring data to and from the phone, now I have an SD card, at least in my current phone, and only real way to move data is to yank the SD card copy and replace. Now for small files (say pictures) I've gotten ssh or samba clients/servers to work well, but only for small data sets. Any large file (A movie, over say 400megs) fails no chance of success, a ROM image at 250meg works 1 in 3 times.
I've fought this battle for years with an SIII (that was decent as at least I did not need to pull cards as they were un-mounted when you plugged into the computer), but remote transfers were a mess. My S4 never worked well, nor has my Note3, Nexus 5's or my current Note4. MTP is a nearly useless protocol (on Linux it is even worse than useless) and pulling the SD card is a hack. Now the network connection is not bad as I have 0% packet loss and I can download the same movie via HTTP from a local server, but that is also not always practical, since it requires getting the phone and moving the file to a location where the http server can locate it extra steps.
What I want is to have the Phone auto start a server (be that samba or ssh) when connected to my home network and then allow for transferring data (real data of any size). It is the transferring that is my issue, the autostart is simple with Tasker and works well enough. I've tried many different ssh and samba Android servers without much difference, and also different networks.
I also want to mention that downloading a movie to the phone is about 12 to 15 megs a second, yet to upload using ssh or samba is about 1.2 megs a second or 1/10th the speed, it should be at least 8/10th the speed. I assume the failures have something to do with Android interrupting the server communications as a notebook on the same network running Linux never fails. Cloud drivers are slow and impractical (however do work in a pinch) as it is also multiple steps and requires me to move data to a remote location I do not control.
My question is how have other people handled this issue with Android?
Thanks,
ERIC

[Q] Only about 3 MBps transfer speed between PC & Android phone via Wi-Fi?

Hi all.
I recently got the Z3 Compact and was enthusiastic about its WiFi transfer speeds when connected to my PC. My earlier phone the Nokia 5800 XM did it at a pretty good speed, and so I was expecting the 5 year jump to a new phone with newer technology would have massively improved on the network file transfer speed.
I tried 2 ways to transfer huge files (1 GB+) to and fro between my PC & the phone.
1.) I used the a couple of the many WiFi Transfer Apps, including Wifi File Transfer Pro & Airdroid.
2.) I turned on an FTP server on my phone via the FTPServer & My FTP Server apps, and then tried the file transferring using FileZilla on my PC.
However, even after using both the methods, I noticed that I was only getting speeds of about 3 MBps. I read in one of the forum threads that the speed might be getting slowed down due to "encryption" while using a non-ftp server based method, and that is why I gave the FTP Server method a try as well. To no avail though.
My Wi-Fi router is the Digisol DG-BG4100N and it boasts of bollocky 100 Mbps+ speeds. My PC is the Asus SX086D K55VM.
What am I doing wrong here? How do I get a faster transfer rate? Xender easily does 5 MBps on an average between two devices. Surely, the PC should be able to equalize that speed, if not better it, right? Thanks a ton for any suggestion you'd like to make, including your own method of the fastest wireless file transfer method between a PC and an Android device.
EDIT - This is the first time I'm posting a thread here at XDA, kindly advise if I have posted it to the wrong sub-directory.
