NFS can be a real performance killer, but to be sure I'd strace (with -tt) a dovecot process and check where it spends most of it's time.
Especially NFS with blocking writes on large files.... Done badly, with the wrong file system I've seen servers disks trash continuously, and IO down at something resembling paper tape (well I exaggerate slightly).
Check the NFS time for copying larges files, compare to say FTP, NFS should be slower than FTP, but only says 20% slower....
