Very High CPU usage (100%) from just browsing the Web

I tested on Firefox and Chromioum. Im at 100% while loading pages which causes them to load slow and when I dont have a application running Im at 40% CPU (At least)

Everything is slow basically. Im also already on Ubuntu Classic so im not using Unity. Should I go to 10.04? is that more stable?

On windows this wasnt an issue. I have a Dual Boot with XP and a 2.4Ghz Intel Celeron with 768MB RAM and an Nvidia 6200 Graphics card.

I heard 10.04 was the most stable. any suggestions?

Solution 1:

Little bit late on this one, but I'll almost guarantee its a flash issue, look for npviewer.bin processes (attached to Chrome or Firefox processes), and kill it/them. I've had it for a long while and seems to be consistent across all browsers when Flash plugin is in use.

I've noticed certain sites are much worse than others, and it'll usually be one tab that's causing it.

Hope this helps!

P.S Anyone know a fix to this issue?? I'm assuming as its flash, its closed and nothing can be done, but there must be a fix somewhere down the line!

Solution 2:

What process is taking all of the CPU? Sounds like the browsers aren't the root of the problem.

You can find out using the 'System Monitor' utility (System->Administration menu). Select the 'Processes' tab, and sort descending by CPU. Or, you can run 'top' in a terminal window and sort by CPU (if not doing so by default, type 'OK').
