[Q] Just-in-time Compiler - Sony Ericsson Xperia Neo, Pro

Hi guys.
I know that most would be unconcerned due to the fact of the "new" and fast processors on the 2011 xperia line. however, would these phones benefit by using JIT, or are they using it already?

I believe JIT already pre installed in gingerbread (2.3 and above)

[Q] Any reason for Vibrant on Froyo /w JIT getting such low Linpack scores?

Is there any reason why the Vibrant with JIT enabled running Froyo would only be getting 14MFLOPS? Considering an overclocked G2 gets nearly 50. . .?
There can't be that much of a difference in the processors. I compared my Vibrant to a friend with a G2 on a few intensive web sites and him running at 1.4 was just slightly faster than my Vibrant at 1.2 running on 2.1. Now provided its not any sort of benchmark or anything, is the G2 really that much faster or are the currently released Froyo leaks with JIT enabled just not finalized?

my guess would be that Froyo for the Vibrant is just a port, and while it may be stable on the Vibrant, the Vibrant is still not fully conditioned for it.

[Q] Can the mini pro be updated beyond 2.1?

I just got a mini pro and i like it, want to keep it but i read that the mp won't be able to run 2.2 due to hw limitations. Is this true? I can't get a clear answer and se are not being very forthcoming.
My concern is that the mp will become outdated in a year (i'll be on a contract) unless i root it but it's under warranty so that's not really a consideration at the moment.
I have an option to return the phone and exchange for an htc wildfire but it's dependant on whether the mini pro can run versions of android beyond 2.1 and how future proof it will be, even on 2.1.
Cheers.
Currently noone can update the x10's. While everybody is expecting 2.1 to arrive any second now, many think it'll be very unlikely that we will see any major update beyond 2.1.
That said, in the future it might be possible to update beyond 2.1 through root, flash etc., but this will forfeit yoiur warranty.
I don't know much about the Wildfire, but as it is from HTC I think it will see more future updates.
On the other hand, the X10 mini pro will remain a good phone, so I personally don't see the big nessecity yet in future updates. Also should we get major future updates, the phone should be able to run 2.2 without problems. Android 3.0 I don't know.

Ok thanks. I was lead to believe that the mini pro wasn't capable of running anything beyond 2.1. It's good to finally get a sensible answer!
The battery life on the wildfire is supposed to terrible so i'd rather keep my mp and anyway i don't fancy having to set another phone up, i've just got it set up how i want. My other option is a W995 but then i'd miss out on Android...
Is it really likely though that SE won't update their xperia phones beyond 2.1, even the X10?

Both mini and mini pro have better h/w than htc wildfire. Wild fire sports a 528 MHz 7225/7200a cpu, while mini/pro has 600 MHz 7227 cpu.
So, if wildfire can run froyo, so can mini/pro.
Whether we will see a future update from se for 2.2, is another question..
Knowing SE, I doubt that they are ever gonna make 2.2 available on x10. I could be wrong in my assesment though..
But we can always count on our own xda developers to crack the bootloader and make custom roms for it.

I thought it was the ram that determined the phones ability to run android. I read that a phone with less 128mb can't run 2.2, well not very well. That's what i was trying to find out from SE but couldn't get an answer.
I've seen the X10 2.1 vids anyway and it looks pretty good. Like bootchee says it's a good phone which is it's purpose fundamentally! The other stuff is icing on the cake but i've seen some pretty cool vids of the wildfire on 2.1, everything running superfast. The wildfire seems to have a lot more options and just overall better functionality as a smartphone.
Guess i'll just have to wait and see what the update brings.
I just want to reiterate the question. Can the mp definitely run 2.2? If not i have to consider whether i'll be happy with 2.1 for 2 years. Also what are the benefits of rooting? I read that 1.6 rooted with titanium backup was as good as 2.1.
RAM is very subjective. It depends on how many apps are open. Since google in their brilliance decided to build an operating system that keeps all apps open until the memory runs low, it's quite possible that 128mb of RAM isn't enough to play HD games and movies, but on a 320x240 screen why would you want to.
Secondly, the x10 mini has 170 mb of available RAM, not 128mb. The actual NAND chip on the phone is capable of 256mb RAM and 512mb ROM, so obviously SE have thought about "future proofing" the device to some extent. Why they limit it to 128mb available RAM and 256 accessible ROM I have no idea.
In answer to your question, if SE decided to carry out a few tweeks and workarounds here and there, then yes the X10 mini is more than capable of running Android 2.2. The 256mb minimum RAM you read about relates to the amount of RAM available to the OS. It has nothing to do with minimum hardware requirements for running FROYO.
The wilfire has a bigger screen but a slow (outdated) processor, which combined with HTC's bloated "SENSE", results in terrible lag, even on 2.1. I would hate to see it running 2.2.
I think the definitive answer you're looking for is "NO" don't buy an X10 mini if all you want is a 2.2 update, because at this stage it is unlikely SE will upgrade the OS to FROYO. HTC have promised a 2.2 update for the wildfire but I doubt this will go through, due mainly to stability issues. If you're that concerned go to youtube and watch some videos of custom 2.2 ROMs running on the wildfire - I think you will agree it's terrible.
Another option to look at is Huawei. They are releasing some very affordable handsets running 2.2 over the next few months.

Hello,
thank you for the information, I was wondering why "cat /proc/meminfo" giving me so strange amount as 169688kB. Why isn't SE using all possible memory?
It's a marketing? If some memory is blocked, probably without recompiling the kernel is not so easy to enable it...

Thats the amount of RAM available to you..
169688/1024 = 165 MB (approx)
I remember reading somewhere, dont remember where, that ram and rom size of m pro is 256 each.

Thanks for clarifying things for me. The amount of false/ misinformation out there is unbelievable!
To give the hardware that capability and then stop at 2.1 makes makes no sense. This is what i'm getting at with SE! So i take it MT and 16m colours are well within the capabilities of the X10?
Are they limiting the hardware so people will have to buy newer versions that run 2.2 and above? That's how it looks. Anyway SE claim that the 2.1 update will be equivalent to Android 2.2. Not sure how as it still won't play flash or 2.2 android apps...
Anyway i don't know if you read my first post but i already have the mp. I can exchange it for a W995 or a Wildfire but i like the mp and the android capabilities are great! It's practically free with the contract i'm on so in 6 months i could trade it in or buy another phone with better capabilities such as Huawai.
I'll check the htc out a bit more but from what you say it's off the table. That leaves the W995. I think i'll keep the mini pro and i'll keep an eye on the upcoming android phones.
If SE stop at 2.1 what about developments with xda? Are custom roms above 2.1 possible or will it be determined by the caps SE have put on the hardware?
Cheers!
In 2.1 update the available ram increased from 165mb to 176mb

How come only part of that is available?
this was something I've been wondering too. why limit the ram? isnt more better?
unknown13x in another thread has stated that SE has skipped 2.2 altogthr nd is working on 2.3 for the new devices. 2.3 reqs same reqs as froyo, so if we can run 2.2, we can run 2.3. All depends on SE.
@all: first of all thanks to the most advanced and leading forums in the field.
i would like to know that i have right now 2.1 update 1 on my xp 10 mini and there are updates also like 2.1 update 2 and so on... so will be able to update it and when they are coming???

[Q] What has Samsung optimized in the latest builds?

I'm very curious if any devs have dug into the latest leaks to see what had been changed. These latest stock roms are spitting out linpack scores of 14.5 on average, which is in many cases better than older kernels and roms running ext4/voodoo lagfix. Have they changed the file system themselves? What's up?

The newer builds are based on Android 2.2 (Froyo), which includes JIT compilation for Java. Java is an interpreted language, which can take much longer than native code to run. JIT compilation fixes this issue by compiling native code from Java on the go as the program runs. This brings a big performance increase for Java code like in the large majority of Android applications (although not much for us Galaxy S users unfortunately- other Android phones like the Nexus One are getting 40 MFLOPS in Linpack). The Linpack benchmark for Android is Java based, so this is why the scores have increased. Not necessarily any other sort of optimization has been done by Samsung. Maybe just a few tweaks.
Ahhh..that's right, I completely forgot about JIT. Hopefully google will focus on optimizing for the Hummingbird now that their latest flagship phone is powered by it. Unless, of course, their goal is to only please the masses being Snapdragon.

[Q] MYriad turbo boost

X10 only not interesting about HD2 or other​ Myriad vs JIT
How to implement this in X10?
using i.e adb??

Just googled it and the latest news I found were from about february 2010. Since both were developed at about the same time, I think that Myriad died when JIT made the race. And no, you cannot have both versions Just enable the flawlessly working JIT if you haven't already, and enjoy your snappy x10
Cheers
How ask never get lost! does it ?
By the way I don't like to threat flashing X10 like a morning sport So I ask!

Hmm... Just wondering if it would be possible to use both of them at once.
As far as I understood IS Myriad providing an other Davlik VM Engine, to replace the stock one.
While JIT is the way the Data is processed.
Does anyone know more about that stuff?

well with JIT u change the DVM is not only data processing, so i think its the same

But, as far as I understand, its not another virtual machine for Android.
It seems to be a VM for other Linux Based OS to make them able o run Android Apps?!?

[Q] Dual-Core Utilization: Should we expect a performance increase from JB/ICS ROMS?

After some reading, I reached a conclusion that gingerbread doesnt have "dual core capable applications support". It seems capability was planned to be introduced with Android 2.4, which has never existed. It was first brought in Honeycomb (if internet is not fu*** me )
So now, will JB/ICS roms bring any performance increase to our Atrix? Or will the difference be negligible? I appreciate if a DEV could answer this.
The GB roms already support all the best games available in the play store, which require some good horsepower to run smoothly.
So, I'd say the dual core compatibility already existed, though it would be improved with the new OS versions.
Hope this helps.
