Huge system's load on entering to Ubuntu (and sometimes when I already entered)

[Nicholas Shatokhin]

When I just enter to system, indicator-multiload shows me a huge system's load (two or three minutes) and all works slow. And this not only on entering. Sometimes, system became slow when I enter few hours ago. I don't know why, but I see it on my work computer (that has eclipse, clementine, rabbitVCS, opera, qutim, filezilla gnome commander and standart programs) and on my laptop (that has clementine, umplayer, qtcreator, qutim, opera and standart programs).

In these moments memory usage, network's, hdd's and processor's using are normal, but system slow (and indicator-multiload shows huge system's loading).

Could you open a terminal and run the command 'top' to see what is consuming a lot of CPU? You can upload a screenshot of terminal window to this bug report.

Hm, top shows that problem not in Unity. It's in Opera.

[Marco Biscaro (marcobiscaro2112)]

Yes, it's in Opera (although the flash plugin and compiz - bug #803943 - is also consuming a considerable amount of CPU).

[Nicholas Shatokhin (robotex)]

I ran top at my laptop without running opera and flash. I saw compiz takes 80% of processos and maximum system's load on indicator-multiload.

So, maybe this bug is a duplicate of bug #803943?
