I have laptop HP 6720s. This happens when I enter top in Terminal:

Cpu(s): 1.7%us, 1.0%sy, 0.0%ni, 97.0%id, 0.3%wa, 0.0%hi, 0.0%si, 0.0%st

Mem: 2053924k total, 1837352k used, 216572k free, 56876k buffers

Swap: 2929660k total, 68k used, 2929592k free, 1196700k cached

I have INTEL graphics card. Applications opens really slow but wireless is really fast. Operations inside applications are slow, too. I have Ubuntu for the first time, I totaly moved Windows 7 to history :) Hope Linux is not this slow usually.

Please help.

what do you mean by "wireless is really fast" compared to "applications open slow" - how are these observations related? What "operations" are slow? – fossfreedom Jan 21 '12 at 21:28
They are not related, I apologize if it sounded like that. Applications opens slow, and every operation I do in applications like Ubuntu software center is slow. I click and then I must wait a couple of seconds till operation completes. Is there any problem with my graphics cards or RAM? – boofighter Jan 21 '12 at 21:38
Seems strange - ok, lets first see if this is a compiz issue - please login to unity-2d and see if your problem is resolved. This Q&A should help you if you dont know how to log in to unity-2d - – fossfreedom Jan 21 '12 at 21:42
I tried that, and it is faster performance. What do you suggest then? – boofighter Jan 21 '12 at 21:55
So I should always start unity-2d and the problem is solved then? – boofighter Jan 21 '12 at 22:03

If this is a compiz issue then you can use Unity-2D to see if performance increases. Unity-2D does not use compiz.

If you find that it is a compiz issue, then you are most probably affected by this bug-report.

This has been resolved and is awaiting testing by a larger group of users. If this is successful the fix will be released into the main repository and you will automatically receive this as part of the Update-Manager process. This will normally occur in a few-days/weeks after a fix is released into the proposed repository.

If you are feel you wish to contribute to the testing process, you can enable the "Proposed" repository in your software-sources. Refresh your software sources via Update-Manager and you will see new Unity packages available. You could install these suggested packages.

It's very annoying when people say things like what do you mean by "wireless is really fast" compared to "applications open slow". I have had various versions of Ubuntu now, and yes, 11.10 for me has fast wireless with slow applications, exactly as said. This is quite a clear description by boofighter. These observations are obviously related, as the slowness is not an Internet/downloading issue. Will also investigate Compiz.. it sped up version 11.04 for me, though was still a little slow.
