Hi,
I'm trying to decide if I could use you mail server in our enviroment which has about 10k users and mailboxes size about ~1GB.
So I made a few tests and it all worked quite fast, except that select
command on large mailboxes. The first time I select a mailbox which has
10k messages it takes about 4s to process. I am deliberately trying
this on a Celeron 850Mhz, 512 MB memory and some shitty hard-drive to
maximize the times.
So why is this so slow? Does it index the messages on select? It's even
slower when I have some new messages in folder, more that I have more I
wait. So I presume it must be something with indexing? Anyway, how
could I optimize this? Why don't you index when a mail arrives instead
of on select?
Thanks for help and keep doing a great job with Dovecot.
