I’ve had a number of coworkers report that their Finder has been behaving poorly since the upgrade to Mavericks. They have noticed that when opening a new Finder window, the window will remain blank and beach-ball for 20-30 seconds before filling in as expected, then seeming to work fine. I was able to resolve this issue by removing the Finder plist and restarting Finder. You can accomplish this by entering the following two commands in Terminal:
This is not to say that this will resolve every Finder issue out there, but of the 6 coworkers that reported this problem to me, it was able to resolve all 6 of them. I figured those were good enough odds to post it as a possible fix.
