mynewstate is taking 8s to run, and very little of the time is taken up in local subroutines. auth_unix.c:mynewstate calls getpwnam, and then iterates over all the groups using getgrent(), checking to see what groups the user is in. The fact that imapd does this twice might be a bug, but even if it didn't do it twice, it would still be slow. Is running "getent group" slow?
We had to patch this out of our Cyrus frontends using LDAP as well because it iterates instead of retrieves. We just decided not to support groups in the ACL's.
I'd suspect this is exactly whats going on is this code is still there in latest Cyrus and it's building the ACL representation. If you don't care about groups you can find, and remove, that code as we did.
