Agreed -- I just ran a non-scientific test for you, as I was curious myself.

Server A: SquirrelMail 1.4.5, Courier-IMAP 3.0.8, NIS+ lookups and NFS 
mounts to /home, Maildir (existing production, rock solid)

Time to open my mailbox: 36 seconds (*)

Server B: SquirrelMail 1.4.9 (in Courier config), Dovecot 1.0rc22 
(Courier namespace mode), PAM/nss_ldap lookups with same NFS mounts (new 
beta server)

Time to open my mailbox: 4 seconds

Obviously there's a million factors (distro release, CPUs, memory, load, 
etc.) but across the board my beta users see astounding performance 
gains. Doing searches inside Thunderbird on random strings exhibits the 
same behaviour, what used to take a minute takes 2-3 seconds now.
