Slow Finder refresh in 10.6.7

Question

Has anyone else had a problem with Finder taking 20–30 seconds to refresh when new files are created in 10.6.7?
E.g., printing a document as a PDF to Desktop -- PDF does not immediately appear, but if the operation is tried again, I'm asked if I want to overwrite the existing file; so the file is there, but not yet visible. A few seconds later it pops up.

For general speeds issues here's what you want to try:
PRAM/NVRAM Reset: Turn on the computer holding CMD-Option-P-R (Command-Option-P-R) and keep holding until you get a second start up chime (more are perfectly alright)
Clear the caches: Go to each users home folder by opening up finder. Go into the Library folder and find a folder called Caches. Drag that into the trash. Do it for all users, restart and empty trash (files are still active so you can't delete until restart)
Then you want to go into Safari on each User and click on the word Safari in the top right hand corner. Go down to Reset Safari and have everything checked but: Reset topsites, clear history, remove other autofill form text, remove passwords
Shut down your computer, on boot it may be a bit slower because of all the resets it's auto regenerating a bunch of files, but over all your system should be faster
Specifically for you two, the caches folder removal is the most important
