Why ubuntu 12.04 Operating System too slow..?

Question

I was using ubuntu 10.10 from last year. every thing was Ok with that. recently I've installed Ubuntu 12.04 in place of 10.10, after installing that on my Dell laptop, I started to feel uncomfortable.

It to slow event if you move mouse then its feel like i'll take 1min to move one place 2 another..

I know why this is happening, all because of 12.04 runs my CPU up to 99%-100% all over time.

And there are 2-3 processes who use all the cpu.. like
1. System_Monitor
2. compiz
I don't know why its use all the CPU even Other app can't able to run .. in Ubuntu 10.10 every think was Ok..

Any solution for this problem..!! |

Thank's

Solution

Not talking about 100% cpu here but this bug is responsible for significant cpu usage on 12.04:

Fix is URGENTLY needed. But until that is available, no solution seems to help.

And what might those 2-3 processes be?
