Since upgrading to Mavericks, Finder sometimes hangs when I select a folder and am waiting for its contents to populate the window. This happens primarily in Open dialog boxes:
It'll spin for about 15-30 seconds before showing the items in that folder. I can "Go to folder" and it'll usually show the contents immediately in that case. Why does it spin, and is there a way to make it faster? (It should be instant. I don't go to folders with thousands or even hundreds of items.)
Clarifications: These are just regular, local folders, usually in my home directory... not Remote Disc or network shares or anything fancy. It's an early 2013 Retina MBP, so it has a solid-state drive.
