Fixed now in v2.0 and optimized also conversion to uppercase: http://hg.dovecot.org/dovecot-2.0/rev/de2798fbbae6 http://hg.dovecot.org/dovecot-2.0/rev/23858ce6422e After this, searching your spam mailbox goes from: v1.2 OK Search completed (26.084 secs). to v2.0 OK Search completed (2.172 secs). It's still slower than v1.0's 1.83 secs, but the increased slowness is most likely because v1.0 didn't support case-insensitive unicode searches.
