Got my Vision repaired - keyboard was broken.

Now I rooted it again, did a clean install of Elitemod (4ext, DataSwap, SDext etc.) .. and it's running kind of choppy. Homescreen scrolling is.. not really slow, but not nearly as smooth as usual.

To check if it's just a random error I flashed a nandroid backup I made before. That did nothing - as choppy as the clean install.

Before I do anything stupid - any suggestions what could have gone wrong or what I might have forgotten while installing Elitemod?
[G2 and Desire Z Android Development] rirozizo:
try removing swap (dataswap, sdswap), cuz it may increase multitasking, but at the cost of some I/O performance

———————————————————

i didn't mean to mock you or to offend you in any kind of way
[G2 and Desire Z Android Development] Kueber:
May be, but I was using 64mb Dataswap before (no sdswap) - why should it cause problems out of the sudden?

/Update: Wiped everything, started from scratch, no sd/dataswap mods.. still choppy. Doesn't even matter which launcher I use, every launcher has the same choppy behaviour.

.. will check some other ROMS and their performance on my device.
[G2 and Desire Z Android Development] rirozizo:
i just flashed this ROM today (yes, i got away from my BlackICE... but i'm still updating it).

using sd-ext: 1.5GB

dataswap: 96MB

latest kernel

gtalk mod

and it is smooooth... you know, if you restore a nandroid backup, the ROM will be choppy... even CM7.

———————————————————

i didn't mean to mock you or to offend you in any kind of way
[G2 and Desire Z Android Development] demkantor:
why would a nandroid backup make a rom "choppy"?

anyway, did you make sure all partitions are formatted to ext4? you said you have 4ext recovery but didn't specify what everything was partitioned to. also when you say you wipe clean are you using a superwipe script? fastboot -w? or just selecting wipe this/that in recovery?
[G2 and Desire Z Android Development] rirozizo:
i don't know, it just lags a little when i restore a nandroid backup... it's realitvely slow comparing it by a clean flash.

[G2 and Desire Z Android Development] demkantor:
just sounds strange that this would be the case, personally I've never had that issue
[G2 and Desire Z Android Development] Kueber:
Okay.. that's strange. As I said, I also did a clean install. Will try that tomorrow.
[G2 and Desire Z Android Development] buxtahuda:
Yeah, I've never noticed hits to performance by backing up and restoring. All it is is imaging your partitions and formatting them where needed, shouldn't make anything choppy.

Anyway, I don't know what to say that hasn't already been mentioned, but I'm decked out (all ext4 partitions, largest dataswap, OC'd) and it's surprisingly smooth. Even runs Electric Sheep live wallpaper at an average of 15 FPS which seems to be about as good as the app can consistently perform across devices. Two or so days battery.

Only chopiness I've ever experienced was due to the fact that I hadn't moved over to 4EXT from CWM and so I hadn't changed my partitions to ext4. Also didn't have the dataswap applied at the time.
[G2 and Desire Z Android Development] nik3r:
Hmm, the first-time media scan can hog the CPU and cause some heavy chopiness. If you have a large amount of media on your SD this can take pretty long as low priority task. Logcat would show the files being scanned though, check it out or just let it run idle for an hour for the scan to finish.

[G2 and Desire Z Android Development] Kueber:
Good idea, will do. But the SD card was completely clean as well .. Maybe that was the problem, lol. Perhaps there is another thing going on in the background.. It's very strange that ONLY the launcher is annoyingly choppy.

Will do a 'clean' install again - any suggestions what I should use to wipe my device? 4ext recovery is installed - will a "factory reset" via recovery suffice?
[G2 and Desire Z Android Development] seeeeew:
No, it won't. Wipe /data, /cache, /sd-ext, then re-flash the zip(s).
[G2 and Desire Z Android Development] Kueber:
Factory reset via 4ext recovery wipes /data, /cache and /sd-ext - zip flashing will be mandatory since I'm running Flinnys JB testbuild at the moment.

I asked because I'm uncertain if there are wipe 'tools' that are 'better' than a simple factory reset via recovery.
[G2 and Desire Z Android Development] nik3r:
I use the last option in wipe menu when switching ROMs - "format everything (except sdcard)" option. EFS wipe is performed by the EliteMod/Kernel package automatically.

@Nik3r, did you try disabling CPU rendering?

http://xdaforums.com/showthread.php?t=1877183

i tried and it's smoother than with CPU rendering ON.

EDIT: btw, Sense 4 style recent apps is like playing crysis 2 on a pentium 4 PC... it's crazy laggy, dunno if it's like this, or because i disabled CPU rendering.

[G2 and Desire Z Android Development] Rozza C:
Using Recent Apps on any setting lags for me...

I've found the WebOS version to lag the least, however..

As for that CPU Rendering disabler...it looks interesting....may give it a go...
[G2 and Desire Z Android Development] Kueber:
Installed everything again from scratch (4ext 'wipe every partition', 1gb SD-ext, 64mb dataswap, checked that every partition is 4ext) - no issues present. However, homescreen still doesn't feel entirely smooth - I guess I'm just spoiled now because of my Nexus 7 :D

Pretty good performance nevertheless. Thanks for everybody's suggestions.
[G2 and Desire Z Android Development] rirozizo:
since I/O is decreased when using sd-ext, and dataswap, i figured i'd see what those I/O schedulers are.

i'm now using deadline while charging, and opening apps is much faster. sio has its problems in I/O, it's battery friendly, but slow. noop is good for normal usage.

so deadline was best for me

Experimental kernel with USB host

I put up an experimental new kernel with USB host hopefully enabled for testing only. Please tell me if it works or not, I have no way to tell.

All the latest changes are also applied and raging at 4827 antutu points (1.9GHz). I also enabled some tweaks that might have similar effect on CPU like hyperthreading on PC.. sort of.. we'll see if it actually helps :D

Please be aware that the 120613-12 kernel currently has broken mass storage function when connected to PC. Something I did, too tired to fix it now.

Please test and report your findings :)
[G2 and Desire Z Android Development] contro19:
I'm unable to reboot... the reboot screen just hangs. I'm forced to do a battery pull. Alls I did after the sign in reboot was install apps from Titanium just apps nothing else.
[G2 and Desire Z Android Development] nik3r:
That can happen, either AOKP or the kernel can get stuck at SD unmounting script and never actually reboot. You can see the LWP moving so it's not frozen, just waiting for something when it should trigger reboot. Battery pull in that case is safe.

I haven't have this happen for some time now so the next release may fix this. I suppose you have sd-ext? If not this would be more weird.

And off the topic: I flashed the European_Asian_lib-ril_gps_updater_V2.26.13.04.19radio_Android_4.x.x.zip and now I am unable to place a stable call. It lasts for at most 10s and then is dropped by provider, so I won't be merging this to the main build after all. I could however use the GPS driver from that package if it proves to be stable and solves some problem somewhere. You can apply the package yourself if it works for you. I would hate to force people to use a single radio version with this ROM, especially since I have no problems with data whatsoever over here.
[G2 and Desire Z Android Development] robuser007:
Calls work fine here :)
[G2 and Desire Z Android Development] terrormattie:
Woow, this rom makes my device faster than my Acer A500 tegra2 tablet clocked at 1.5ghz running stock 4.0.3. How is this possible? Either way thanks for this awesome rom!
[G2 and Desire Z Android Development] contro19:
I actually formatted my sd card as per your instructions here: SD Format Guide

I did everything your guide said in regards. I'm sure it's just a glitch. I was able to reboot into recovery with no problem last night thought which is good.

The only major problem I'm having now is my battery is all out of whack... I have had the original battery since the phone came out I think a new battery purchase is needed in order to fix that.
[G2 and Desire Z Android Development] Jivebunny:
Experiencing the same issues. Using setcpu with settings from n1k3rs 1st post, OOM regrouped with android.mimic.ca. other than those two things, it's fasttttt

Absolutely amazing.

[G2 and Desire Z Android Development] xhitz:
@nik3r Yeah it is weird that it is weird that it wouldn't install! and everything was in EXT4 I actually partitioned (in 4ext) a brand new sd card before i put this rom on it! It jsut wouldnt install for some reason untill i hit the option "Format All" but there are a few problems im getting

1. The PowerSave mode disappeared after I enabled all the StartUp scripts in Rom Control, I even added a shorcut to the desktop for the activity, but it gives me an "Unexpectedd Error" (I think it was a problem with the runtime java" or something idk?

2. The web browser when viewing sites with videos on it when I clicked to play them (On Mobile Sites) open'd up QuickPhoto and it said it couldnt play this video? MP4/MP3 formats as well, but desktop versions played just fine except for when i clicked the video to full screen there was no option for Volume or the "Play/Pause /Loading /Foward n Back Skip buttons were not displayed? It also played the videos fine after I would download them instead of streaming? Could this be a DPI setting issue?
[G2 and Desire Z Android Development] Stevennnn:
I appreciate that you say there is a chance this is just the placebo effect,

hate it when people state their opinion as a fact without proper testing.:)

OT:

At first my data and cache were in ext3, I'm not sure what caused that but after formatting to ext4 (with 4ext recovery) my phone runs really smooth with this rom!
[G2 and Desire Z Android Development] nik3r:
Yes, sometimes very subtle changes may provide tangible benefits while big "overhauls" will do basically nothing unless in very specific scenarios.

Right now I'm trying to compile CM9 source to make my own modded sqlite3 libs. Basically I want to increase performance without introducing the annoying bug that makes for example K9 emails open ridiculously slow. Looks like some apps are actually waiting for the SQL to write to storage before continuing (some sort of transaction emulation perhaps). By making SQLite not write to the storage during execution it makes it incredibly fast in 90% of scenarios while basically breaking it in the rest of cases. Took me a while to figure out what was causing those lags. I want to settle for middle ground here ;)

Does anyone here have experience compiling CM9 from source if I have problems? I think I'm on the right track though it's just taking really long. At first I tried to cross-compile sqlite3 from official sqlite source only to find out android has it's own heavily modded version and the standard won't even boot.. great :D

I'm loving this ROM so far! Up until now, I tried almost every ROM but always ended up going back to Virtuous Sense 2.0 because it was just so smooth. I think I might be keeping this ROM until I get my phone upgrade.

One thing that I'm wondering though is about screen rotation. When I am in apps like Dolphin Browser, or any app for that matter, I have to flip out the keyboard in order to get the screen to rotate. Is this supposed to be this way or is this because of ICS compatibility issues with our phones?
[G2 and Desire Z Android Development] nik3r:
Just enable it in display settings, it's always been there ;)

I have it disabled because I am a bed reader. You can imagine what auto-rotation does to me :D
[G2 and Desire Z Android Development] d@rklink:
Wow..... I feel like such a dummy. I checked all of the Apex launcher settings thinking it was in there somewhere and never thought to the check the actual settings. Thanks!

EDIT: On a side note, does anyone know if Apex Launcher Pro has widgets? When I was using Android 2.3 ROMs with Launcher Pro, the paid version had HTC Sense like widgets. What I'm really looking for is a contact widget that can display my favorites contacts on the homescreen.
[G2 and Desire Z Android Development] nik3r:
If you don't want to pay for such a widget, you can just place a shortcut to a contact on homescreen. Or make a folder of shortcuts like a fast dial button.
[G2 and Desire Z Android Development] Chillout:
So I finally moved to ICS... :D

Could it be that UV is not supported yet?
[G2 and Desire Z Android Development] johrie:
Nik3r how is the usb host going? i can test it if you want :)
[G2 and Desire Z Android Development] nik3r:
UV is bugged in the stable release.

USB host should be available in the experimental kernel (with broken PC mass storage/adb but that is unrelated). Try that one.
[G2 and Desire Z Android Development] Jivebunny:
Found one of the causes for slowness. I think I accidentally left the aokp rom control cpu settings 'set on boot' ticked. Took that off and now this thing is purring like a kitten. Only memory tends to fill up too much, but that's being worked on I understood.

1.9GHz... you'd normally get those scores at 1.9GHz.

i'm talking about 1.2GHz smartass.

can't wait for the new kernel.

i didn't mean to mock you or to offend you in any kind of way
[G2 and Desire Z Android Development] nik3r:
Well there's no point benching with smartass or ondemand, it will be different every time. Performance is for baseline comparasm, it is always the same ;) And I use 1.9ghz as my baseline because any aberations are more prominent in high speeds.

And 1.9ghz won't give those scores, last time I tried cm9 at that frequency I got barely 4100 points, this is insanely high even for EliteMod :D

All it took was a minor app cleanup.

Just a little warning...

If you update Apex Launcher...DON'T!

It force closes all the time, making your phone pretty useless, unless you install a new launcher via the Web Store..

I sadly learnt that the hard way...
[G2 and Desire Z Android Development] Kueber:
Yeah did that on my nexus, lol. I just uninstalled it and reinstalled the latest beta. Hope they'll fix it soon, I'm curious how the performance changed due to building the launcher around the stock JB one.

Yeah the beta 5 was pretty useless and much slower. Stick with the one bundled, you can uninstall updates in setings I think to restore speed

Antutu went down, but real-world use seems much smoother. And although the score went down, I achieved much better FPS on the 3D rendering test after disabling software rendering.

Scrolling seems smoother, I'll try the build.prop edits mentioned as well as some others to see if it can't get even better. My tablet has something that supposedly forces 60 FPS, see if the same code won't work here.

Hi this is probably a noob question but is it safe to delete the following system-apps (via titanium backup)

- News and weather (google)

- Movie Studio (google)

or are they connected to other apps/services and will it cause instability?

Thank you for this rom. I have been fighting with other roms after I decided to come back to my HTC DZ, (after from parts swap because the SD card slot stopped working). I kept switching to the latest CM9 roms but I found my phone running hot all the time when playing audio books. So that cut my battery life into 8 hours :( I thought the overheating problem was a hardware fault, I gave up and just started looking at other phones. Just because I can't couldn't find anything, I started playing with ROMs again and found this EliteMod Rom.
