Every since upgrading to Lion my system has started to slow down, big time. I realized that the Finder was using over 100% of the CPU, even when I am really not doing anything with it. I restart it, and after a bit, it is back up to over 100%, making everything else crawl.

I have done a disk repair and permissions repair as suggested elsewhere but that does not seem to help. Does anyone know how to fix this problem?

are you using any network file shares? – Nelson Nov 6 '11 at 22:04
I do, but I connect to them, do what I need, then disconnect. – Nic Hubbard Nov 6 '11 at 22:38

I figured out what it was a permissions issue. Running Fix Permissions in Disk Util fixed the issue. Strange. But, found one other place online talking about this and how it worked for them.

Please attach a screenshot of the Activity Monitor window during this issue, or describe which process in specific. There are a number of these related to functions with Finder or the system that may or may not be connected.
