Hello list,

Currently running dovecot-1.2.16 as pop, imap, and deliver (with sieve). All on 
Solaris 10u9, on NFSv4 backends.

All is working great. But occasionally, the system gets rather loaded, not 
entirely sure what part yet, but as part of researching that;

If we were to start the upgrade path to dovecot 2.0.13, are there any known 
areas of performance increase which should encourage us to do this? Since we 
have a stable system, there is hesitation in changing any part of it :)

Each NFS server hosts about 92,381 mailboxes, LDAP as authentication and ZFS 
user quotas.  What sort of numbers do others manage generally?

Cheers,

Lund
