I looked into Cyrus and found that the setup was not as intuitive as I would have liked. When I started, we had a POS Exchange server (even by Exchange standards this one was garbage due to its setup). We have lots of road warriors, so when I switched to qmail, I also set up maildirs, and served them with courier.
I know lots of people love courier, but I had nothing but trouble with it, especially with Thunderbird clients. Now qmail is gone and a Postfix server is in its place, and courier is gone and dovecot is in its place. This configuration has shown much easier to manage, but also super stable.
The only slowness I have found with dovecot was when I tried to configure it to read account information directly from LDAP. If I go though PAM, which reads its accounts from LDAP, it is fine. I suspect the problem is a PIBKAC error, so don't read too much into that problem.
When I looked at Cyrus, its configuration was just far more complex than I could justify. As for speed, most accounts I have heard from place Cyrus as faster, but not by an amount that I feel would make a big difference in anything but the most extreme cases. From what I can tell, dovecot can more than outrun my fast Ethernet (100Mb). So, therefore, unless you are running gigabit Ethernet, or, you are overloading that machine, I doubt that dovecot is going to create any significant performance problems. Even if you are running G-Ethernet or overloading the machine, its smaller size will probably reduce most if not all the speed advantage.
Good Luck
