I just upgraded to 11.10 and while there are a few problems that seem like they might have gone away (about 50% of the time I couldn't boot properly - haven't seen that happen yet), occasionally my computer slows to such a crawl as to be unusable.
This seems to be at least somewhat related to chromium as killing tabs does make it get a bit better, but I have 8 gig RAM! Sure I dedicate 4gb to a virtualbox vm, but the remaining 4 should be plenty. So keeping an eye on my system resources I see it pretty consistently looking like this:
And this is with only 3 chrome tabs alive, chat, and nothing else really running. Is this normal? What steps do I take to trace down issues? I'm primarily a windows/web developer with at best a tenuous understanding of Unix.
