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?

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.
