I'm curious to hear if you have any benchmarking figures on that (ie, Cyrus is faster than Courier). In any case, for large mailboxes in Maildir format, mounting the partition with the "noatime" option is a good idea. Also, reiserfs seems to have better performance with large number of relatively small files in a single directory (that is what Maildirs do). With very large number of users, you might even want to hash their home directories (like /home/b/i/binand for me, /home/d/e/devdas for you), to speed up directory searches. Again, /etc/passwd lookups too might slow things down, hence it is probably better to use one of the non-authpam modules of Courier (authdaemon+authldap, perhaps - authdaemon can cache auth requests/responses).
