Listing some directories in the Finder, even those with just a handful of items can take 30 seconds or more. Others show their contents in under 1 second. I can stream video and transfer files without issue. I get the same issue with both AFP and SMB.
This is screwing me up most when I try to add music to my iTunes library which is hosted on the FS. It takes something like 5-10 minutes to add one album. When I try to list the directory in Finder it initially takes more than 30 seconds to load. Some subdirectories took as long as 1m40s to load!
Any ideas of what I can do to speed things up?
