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.
