Hello everyone
I'm using DBMail 2.2.10 on debian Lenny 64 with postgresql for mail storage.
My setting is small : 15 users, between 7 and 15 GB of messages stored
in the postgresql database per user, accessed by IMAP.
All clients are thunderbird, either running on windows or ubuntu.
My problem is that my users keeps on complaining the mail system is
often very slow, sometimes they have to close thunderbird and reopen it
so they can at last read some messages. I can't trace whats happening
except that there are slow queries reported in the mail log.
Besides, I've noticed that any message search, even using a webmail like
squirrel mail (which is running directly on the mail server) is slowing
performances for all users. In fact, no one can read (or perhaps even
send) messages unless the search has finished.
The search process itself is horribly slow, and I don't even try to
search word occurrences in mail bodies, I restrict my searches to From
or To fields.
Even like that, I have to wait 5-10 minutes for results. Meanwhile, all
users are stuck.
I can't believe this is a normal situation for such a small setting,
what can be wrong ? How can I trace what is happening ?
Thank you
