Just in case I understand you wrong: You're serving 20k concurrent users with 1 (one) server?
Wait, I think I misunderstood you. We do not have just 1 imap server. We have 30 imap servers (a little overdimensioned at this time). I was just showing the graph of one of them. The others look similar.
Thanks for the info.
I conclude that it is no problem to serve about 1000 concurrent users per server (with dovecot 1.1 probably even lots more!).
Unfortunately I cannot compare this with our setup as we do not have dedicated NFS-boxes (Netapp). Our servers have to do local hard disk IO as well. I think this probably decreases performance (?).
