[Q] Rooting made my phone working slower

---

Hello everyone!
Not so long time ago I've finally rooted my phone - http://forum.xda-developers.com/show...9&postcount=18
Unfortunately there's a next problem... Before I rooted my Desire Z, phone was working smoothly and there was practically no lag. But now my phone is working much slowly than before, even when I'm using Advanced Task Killer to reduce active applications. It lags when I'm browsing applications, when I'm opening them (now after choosing application to run my phone is not responding for about 10 seconds, before there was not problems like this) and some other situations.
What is a cause of this problem and how to make my phone running like before rooting, or faster?
Thanks for advance.

Don't do that.

Which rom are you running? Using task killer will just make things worse, 90% of the apps you see in the backround need to be running.

like the last two posts say, dont use a task killer, they cause more harm than good. if you must use watchdog (free in the market)
ok so we need more info, your rooted. what guide did you follow.
power off. then hold down volume down button when powering on - write down everything you see here.
then do you have a custom recovery? did you flash a custom rom? did you do a full wipe?
these are all things we need to know if you want useful help

I would suggest using the V6 Supercharger script(http://forum.xda-developers.com/showthread.php?t=991276). Moreover, you may wish to shift to a different ROM. I would recommend the following:

AOSP: ILWT (http://forum.xda-developers.com/show....php?t=1242480)

Sense: Android Revolution (http://forum.xda-developers.com/show....php?t=1493404)

ICS AOSP: Andromadus Audacity (http://forum.xda-developers.com/show....php?t=1349864)

ICS Sense: Most have certain problems and thus I suggest you hold a certain amount of patience if you wish to Flash a ICS Sense ROM.

Also, you may wish to note some recent non-ICS ROMs already possess built-in RAM optimizations.

Just gaining root won't slow your system down.

Did you flash a different ROM or anything?

And don't use task killers, they are actually more trouble than they're worth. Android already manages applications just fine.

You guys are saying that task managers are bad but im using sense4 and that has a stock task manager. Is it bad to use that as well? It usually frees up a lot of ram

Freeing up ram dosent always equal a good thing. Ram on an android device is not the same as on your pc. Android holds important apps and recentely used ones in ram so we can open apps faster, multitask, not loose important info ie messages.
The system itself will regulate what apps to keep in ram and when to close them down. I suggest watchdog as a task killer because it allows you to see if an app in ram is actually taking up cpu or not. Blindly killing apps often leads to undesireable affects as well as potentially faster battery drain and slower speeds as these "killed" apps try to reopen or are shut down when they should be open.
Do a google search you will find plenty of info on why not to use task killers and why it is ok sometimes
If this won't convince you know that cyanogen won't even look at a log cat to fix an issue if there is a task killer present

+1 to this. Root is just a change in file permissions, it doesn't "do" anything extra that would slow the system down.

Task Killer on the other hand, may be the problem in itself. Task killers aren't needed in Android. Android manages tasks by itself. Killing tasks may actually be slowing the system down. Killing a task before its done just causes it to respawn, sucking up CPU cycles.

Or the issue can be some other change the OP made after rooting. The OP hasn't given much info (stock ROM or otherwise, or other mods) so its impossible to say what may be slowing the phone down.

But when I was using Advanced Task Killer in my previous Android Version (2.3.3; before rooting) I was experiencing a very big performance jump. I've only done these things I've added in my first post. Also I want to maximally increase my phone's battery life.
Which ROM should I use to increase performance and battery life? Cyanogenmod?
