I had to call off the experimentation with live users and resorted to
running all IMAP connections from a single NFS client for now. I was
causing a little too much of a stir. Here are the things I can remember
trying:
negnametimeo=0 (no perceived difference)
acregmin=0,acregmax=0,acdirmin=0,acdirmax=0 (slowed down imap but
otherwise no perceived difference)
stopped statd and lockd after changing dovecot to use dotlock (no
perceived difference)
vfs.lookup_shared=0 (no perceived difference)
dovecot 1.1 (no better than 1.2 regarding this issue)
Did not try (yet?):
udp, nfsv4, freebsd 7
I feel compelled to keep the users happy for now while I look into the
nfs director included with dovecot 2.0 designed to keep individual IMAP
users on their own server, so I'm taking a stab at the recommended usage
with newer software rather than more debugging with previous versions.
I may return to other tactics if the future path slows down,
I'm still curious why things changed.
