As I mentioned earlier It doesnt with squirrelmail, I tried it on production and the I/O increased a bit, watching logging alone was giving me a headache (no, not in debug mode either)..
How much is "a bit" that the I/O increased? Less than 10%?
perhaps around the 10-15% (see below)
So I thought I'd try it on a dev box, in case the cache wasnt large enough, but nope, incidentally imap with evolution works as you indicate it should, but webmail, not a hope in ..... it is login -action logout constantly, imapproxy avoids all this crud, so it obviously does something differently, maybe you find that and incorporate it in dovecot :) that way all this login logout stuff is only seen in say, debug mod?
It still sounds like the only problem you have is the excessive log messages?.. Sure, Dovecot doesn't even try to get rid of those.
this likely is the sole reason for the I/O increase, but yes. Oh and the local (replicated) DB was seeing maybe 40 requests a second rather than only a few, no big deal there though.
