MySQL memory usage

[Drakon]

My performance problem is on searches. I have verified there is not a problem with mysql. I don't know, possibly it's a problem with Roundcube or IMAP. Desktop applications works fine with IMAP. My big problem is with searches, these are very slow with thousand of e-mails. I have disabled plugins too.

Can someone help me?

It is IMAP server performance issue. Ask on different forum/list. The only hint I can give you is to use Dovecot.

Thank you alec!

Ok, I have seen that many people have improved the performance migrating from 'courier' to 'dovecot' because 'dovecot' has indexing for search. I'm studying migration. Do you know if 'dovecot' uses the same structure maildir as 'courier' with folders 'cur', 'new', etc? I need to migrate mailboxes (/var/vmail/*) with a 'dovecot' script in Perl but I have plugins that uses courier maildir references.

Thanks anyway!

SKaero, alec, I solved all my problems migrating from Courier to Dovecot. Now is faster, very very very faster!!

Thanks for your support!
