BTW. What NFS server are you using? The problem is mainly on the server side,
so would be useful to know which NFS server implementations (if any?) can
handle readdirplus without such a huge performance loss. Mainly I'm wondering
about NetApp, since that's what most large Dovecot NFS installations use.
We are using a celerra from EMC, conected to an EMC SAN.
