Anyone else noticing lag with jailbroken 2.2

[Bear Hunter]

From the time I press the SMS, Cal, icon it takes two seconds for the app to open completely. iPod takes less than a second (2-3 seconds if opening for the first time after a reboot), and I'm running a theme that has 3 widgets on springboard.

Are you installing anything other than Winterboard?

The only other app I had installed was SBSettings. My Winterboard theme had no widgets, no rotating wallpaper, nothing fancy at all.

You reckon SBSettings is/was the culprit?

I don't run SBSettings because I thought it was too unstable (going into safe mode after a respring on more than one occasion). I run the regular BossPrefs. So I can't say for sure...but it sure is compelling if that's the only difference between your phone and mine.

Well, shoot. I might just have to re-JB. Yet again.

I do miss my theme, and my less-obnoxious-than-stock SMS bubbles.

i used to use SBsettings but it was a bit unstable, slow and it was the first time i noticed one thing, whenever i went to safari none of the windows had any images cached whatsoever. i guess the phone had run out of memory to even keep a cache of the web page before.

i'm now back on bosspref and it's been great and muuuuch better.

Interesting. Well, I'll give it a go again tonight. I'll post again later with the results!

When you guys are backing up your data, how are you doing it? Is there an app to download or something?

Also, when you say restore with iTunes, do you restore to the 2.1 firmware and then upgrade and then JB?

Ok, well ... either my iPhone is defective, my expectations are high, or yours are too low.

I just restored again last night, and then re-JB. All I installed this time was Winterboard. And once again, there are slowdowns, with even a basic theme (no widgets, no rotating WP, etc) ... I think it's a memory problem, because I I just had an interesting experience with Snail Mail. I played that game for about an hour yesterday, no problem. I just tried it now, and by level five it started getting stuttery and finally crashed. I re-booted, and the same thing happened. Since Winterboard is the only thing different on my iPhone since yesterday, that MUST be the culprit.

Whatever. I hate losing my theme, but this is getting really old. The slowdowns (and crashing!) just aren't worth it.

I wasn't exaggerating on the number of seconds it takes to open those apps on my phone. There is definately something up with yours. I am running 3 springboard widgets (weather, calendar, clock - with second hand disabled) and I can play Asphalt 4 with no jittering or lags.

The only thing I can think of is you did not Restore your phone before you jailbroke and subsequently still have junk on your phone which is causing the problems.

See here about how Cydia just moves things around keeping junk on your phone if you update vs. restore.

http://sleepers.net/2008/09/19/how-to-upgrade-in-itunes/

First off, you never use “upgrade” on a jailbroken device. If you do that, you automatically lose about 500mb of disk space and never recover it until you finally restore. If you upgrade from 2.0 to 2.0.1 using upgrade button, you lose 500mb. If you then upgrade from 2.0.1 to 2.0.2, you lose *another* 500mb. And this continues until you hit the restore button. The data loss is because Cydia moves your files around to free up space. The moved files become inaccessible but stay on your disk which means you essentially just lose the space. The more apps you had installed in Cydia, the more space you lose.

Thanks for trying to help. I actually did a DFU restore last night before I did the jailbreak, just to be safe. So that's not it.

Anyway, thanks again. I wish it worked well on my iPhone, but it consistently does not. Oh well.

I just did the JB on 2.2 and thus far I haven't encountered any lag (I think). I decided not to install Winterboard or any of the other custom preference programs, themes, etc... While I would like a custom (non-black) wallpaper, this seems to be the biggest source of slowdowns. So right now the only things that I have installed are Cydia, Terminal.app and sudo. I tried to kill Installer.app by just deleting it, but I'm sure that there are a bunch of files from it hanging around on the filesystem. I think the most useful part of the JB will be the ability to use tethering if I want to in the future.

Anyone know the su password for 2.2, is it still 'alpine' like it was on OS1.X?

 

[Xtgirl]

alpine worked for me.....

I also uninstalled mobilesubstrate using Cydia and it seems to have accelerated my boot process tremendously. Now I encounter almost zero lag from the JB protocol overall. For anyone that does not wish to use themes or programs that slow down the OS, such as Winterboard, I recommend killing mobilesubstrate--it runs as a daemon on all default JB'ed devices, so it uses some memory even if you aren't using programs that employ it. And I guess with the itty bitty 128MB of physical RAM that the iPhone has to run unix, every single KB of free memory counts.

I do wish that I could have a background wallpaper image, but it seems that all of the theming and customization apps for the iPhone work like Unsanity's APE framework, by interrupting API calls of the native programs and then overloading them with custom 'injected' code. Obviously, all this function overloading is going to add additional overhead to the OS. This might be an insignificant issue on a desktop OS, where one has 2GB-4GB of RAM to play around with, but with only 128MB, it probably becomes a huge resource drain.
