I've tried several CIFS servers, including NetApps, and Samba servers
ranging from 3.3.x to 3.5.2. The CIFS servers are about as good as
they're going to get, based on the performance of a direct copy of a
working copy from one share to another, which only takes a few minutes
for the same working copy.
