Our courier server works mostly ok, but searching in large inboxes takes couple of seconds. Is there a way how to speed up search?Our server is a virtual machine on current generation xeon server: 1 virtual cpu 1gb ram We have disk on 7.2k rpm drive:5gb email in shared inboxes 13gb email in user inboxes (6 users) We have less than 100 new emails daily.I think imap search is mostly disk bound and adding cpu or memory won't help. Is this true?
Correct. IMAP search is mostly disk bound.
If it is so, than moving to ssd should be greatly beneficial. Or would more cpu or ram be benefical?
Another option is RAID, specifically RAID-1. The more spindles you have, the better the latency.
