Yeah but AFP is still performing way better than SMB on Mac for any fast networking. Like 10GigE and faster. Apple SMB stack is a disaster, and thoroughly unprofessional. NFS is faster, too, but unfortunately the Finder, being the rat nest of bugs it is, has often trouble with NFS shares.

IIRC I had some really nasty move/duplication issues with NFS the last time I tried it in Finder.app. (and the whole UID mess)
