When opening some folders, the Finder takes a long time (30-60 seconds) to load all the files in it. Specifically, these folders typically contain 10-50 PHP files (which are text files), each about 10 kb.
I also notice that sometimes, after the files are listed, their icons are still loading and the "Kind" column is also still loading. (I've got the "Name", "Date Modified", "Size", and "Kind" columns showing; "Calculate all sizes" is enabled" while "Show icon preview" is disabled.)
In addition, when opening a directory such as this and viewing Activity Monitor, I see that coreservicesd is at 70% CPU and Finder is at 30% CPU. After all the files have loaded, both services are still at these CPU levels for about 60 seconds afterward.
Anyone know how I can fix this? I already did "Repair disk permissions" and "Repair Disk", along with a ton of miscellaneous Onyx tasks, but the problem still remains.

Hallelujah! I figured it out. Okay, so first thing I did was create a new account, as suggested by another answer. The problem did not occur in there, so clearly the problem was limited to my account. I then went into Safe Mode into my account. The problem did not occur as well. So clearly something was loaded in normal mode but not in safe mode that was causing the problem.
While in safe mode, I then cleared the caches (in Terminal, using
sudo mv /Library/Caches ~/Temp/and the same for~/Library/Caches). Problem solved! I've had other problems as well in Finder so perhaps this will fix this as well. I'm curious as to why using Onyx to clear the User caches didn't clear these as well, but anyway, from what I've read online it seems like getting rid of these two folders is safe. Also, Time Machine never backs up~/Library/Caches(but it does back up/Library/Caches), so that's reassuring.In addition, while this post was made in 2003, it still applied to my situation and this was what convinced me to clear my Caches folders.
