What is JIT? - Hero CDMA Q&A, Help & Troubleshooting

I want to know what is JIT?

Just In Time
Easy answer: It's another method used by Java to speed up application execution times.
Complicated answer: http://en.wikipedia.org/wiki/Just-in-time_compilation

I actually remember discovering JIT when I aas in 9th grade and I started messing around with BasiliskII and emulating MacOS for no reason whatsoever. God, the JIT builds were faster.
It might sound stupid, but is JIT similar to HLE? They SEEM the same, but I'm no programmer...

related q: how to tell if it is working?

Significantly higher benchmark and linpack scores, broken tapatalk, random revolts, and more memory consumption lol.

[Q] Performance help!

Sorry If this seems like a Newb type of question.. But is 26.3 fps a good benchmark score?
I'm Running...
android version 2.2
baseband version 2.42.01.04.27
kernel version 2.6.29.6-cyanogenmodameer darchstar #9
mod version cyanogenmod-6.0.0-heroc-rc1
build number frf91
Is there a way to utilize my hero better?
If I understand it correctly, a lot of these "tests" are subjective and not really an exact measuring stick. I've seen as high as 32.2fps on my hero running PapaSmurf's Blue ROM. I have seen as low as 13fps on an unrooted 2.1 sprint stock ROM. So 26 is very good.
However I consistently get higher MFLOPS with CM6 and Froyo. But it isn't as simple as just saying "I have more MFLOPS so my phone is faster than yours".
Thanks for the info! What are mflops? Also are there any tips to speed up the phone?
I just used linpack and out said my mflops was 2.221?

MFLOPs are "Mega-FLoating Point Operations Per Second" - basically a measure of processing speed.
This is what I got the second time

Thanks! I've tried SetCPU.. Works decently.. Seen a big Diff. Installing alot of apps will slow down the phone.. correct?

Enable JIT, it will more than double. (this does not always translate to a "faster" phone)

You can install as many app as your hero can hold and still not slow your phone down. But if your installing apps that update in the background that is set for short intervals, than yes it will slow down your phone. Just be sure the apps you download that update in background can be set to longer update intervals. For example, if your using a gmail widget that updates your e-mail every 15-30 min, slows it down. Hope this helps you.

The only Widgets I'm running on my phone are google search, SetCPU, Sense Analog Small Clock. I also set up the phone so that I only have 3 screens instead of 5, 6, 7. I'm not too sure if that will make it faster.. I'm just more of a minimalist.

[Q]Remove fps limit.

So, how to remove or increse fps limit?
No one did it yet, maybe because there is no attention from devs to it.
Its a waste of dev time

So we can boost our Quadrant scores instead of getting nothing higher than 56fps in 2D/3D tests. I just want to let it run uncapped and see what it does.
Use nenamark results as a comparison instead then, it runs under the frame limit

I/o boost

Hi all
On of my friends has miui running on his htc desire. As well all know both desire and milestone on stock roms does not have very good i/o. But on his desire with an ext3 partition had a beastly i/o. I mean really beastly. His i/o was the same as his processor score pushing the quadrant total way past 2000. So why is the i/o on miui so fast? Is it because of that i/o performance patch on miui? And can us milestone/droid users share the supercharged i/o love

What do you mean by I/O? Input/Output? Which Input? Which Output? SDCard I/O? User interaction?
Please be more specific

I think he might mean UI..
Nope I mean i/o input output. And this is based on the quadrant benchmarks and I can't get my head around how his i/o score is over 1000.

Depending on which ROM you have, you can get over 1000 in Quadrant. I was able to on Cronos 1.3.0, FroyoMOD 2.7.0 and iceandfire 2.2
How? I'm on iceandfire too but me I/o isn't that high and I have working ext3 on my SD card

What scores do you get? With Quadrant, you need to run it about 3 times to get a fully consistent result.
I get about 250-3300

What's your overclock?
At 1100 I get 1000 minimum... on CM6 I'd get about 1500 alot

First of all, Quadrant sucks. Let's start by clearing that up.
You can cheat, especially with the I/O score. Here is how:
http://www.androidcentral.com/how-cheat-android-benchmarks
Now, if you want scores:
With CM7 and 1GHz, I get 1000.
With CM6 and 1.1GHz I used to get 1450.
Nice cheat heh
300 is freaking low tho

What about gaming and battery life?
Sent from my Milestone using XDA App
I really can't say, as I don't use Milestone for gaming. Only for Angry Birds, and it can be played on every ROM I've tried.
The other day I installed Sacred Odyssey: Rise of Ayden and it plays well on CM7, so I guess it would play just fine on CM6.

[Q] Hit the 5 month mark, should I finally root and lagfix?

I have noticed that when I click a button, I usually have to wait from 1-2 seconds before I get a response. Would lagfix take care of this? I'm running stock Froyo.
As many have stated all the lagfix does is help fix the very slow rts file system, it most likely would not help in your case.
Best thing to do is delete unused apps, and reboot the phone every day or to(seems to help mine out, cant guarantee results)
Also if you havent needed root in 5 months you probably don't need it
Unless you want to use opitimised roms, I dont see why you would need to root. Check your memory usage delete unused apps and reboot the phone ever once in a while.
My honest opinion, no reason to have an android phone if you are not using roms

Gonna have to agree with mcord here. had to go back to stock froyo for about 5 hours (didnt have all my tool to get back my 2.3.4 ROM) and it was horrible.
you might not be up for it but i really recommend flashing a Froyo Custom ROM from one of the xda DEVs. you'll love your phone and be amazed that it can be so much smoother and responsive.
First thing I did after i rooted was flashed a new kernel to overclock. Performance increased but battery life was poor. Then my first rom was cm7..been hooked since..tried miui once then went back to cm7.

Providing arbitrary benchmarks does not seem like an actual reason to employ a lag fix.

No a Benchmark score is not the best example to lag fix your phone ,but the more power you get, plus better battery life and, better perrformance are great reasons to lag fix your phone. I just posted the quadrant score so kb0npw can see the increase performance from normal rfs file system to ext4(lag fix).

I dont think he thought it meant everything, he was giving a simple before and after which showed some improvement. Quadrant can actually be pretty useful when trying to gauge what effects certain changes have on your phone, say you score a 1900 before you change 'x' and then 2200 after that change, then you know its increased performance somewhat and youre moving in the right direction. How much it has increased your performance is debatable, however. My point is quadrant can be a useful tool when making changes on your phone if you take it with a grain of salt.
EDIT: To answer op's question, Read up on some custom roms and flash one, the difference is phenomenal and you'll wonder how you went 5 months without them. If you have any other questions feel free to pm me and I'll see what help I can be

[TIPS] increase 3d performance

Have a big search on xda forum and :
(paste)
Simple, just remove or move libGLES_android.so from system/lib/egl to somewhere else from that folder in case if your system gets unstable while working with 3D app/game. Tested with Quadrant Advanced, got 60+ fps on 3D Planet test.
This mod already does that but in a different way: it deletes libGLES_android.so in /system/lib/egl (you can see this in the updater-script). Like many people reported this boosted their 3D quadrant score and increased FPS in some games. Why? Because quadrant and some rare games conflict with PowerVR GPU cards and use software rendering instead. So by disabling it you force them to depend on PowerVR. Hence, more FPS.
My quadrant score on rubix rom :
without tips : 2200
with tips : 2722
the earth turn at 60fps
the adn turn at 42fps
with chainfire3d (instead of 3d app doesn't work):
quadrant score 2532
Deleting/renaming that file also fixes n64oid. Great find.
Sent from my DROID3 using XDA App
seems to work great. i don't do quad scores, but i play this game called trial x. on my og droid the graphics were fine, but on my d3 under the dirt bike was pixilated. removed that file and now more pixels. so it must have done something positive.
I moved the file to my sd card, rebooted opened up trial x and I still get the pixelation under the dirtbike.

Rather then deleting or moving can we just rename it and it still be affective?
lol my score w/o doing this 2700-3000 multiple tests lol

Hey about to try this out after I make this quick TWRP backup. Anyone have any AnTuTu increases they could post or any other benchmarks or is it more of a behind the scenes kind of deal?
Either way, thanks for the info! Great community here much love:good:
