Hi, I've installed the latest cyrus release and I'm having trouble with large mailboxes. I was going to try if the 4Gig limit is gone and I'm filling up a mailbox with mails. If I open the mailbox trough mutt it gets loaded at a acceptable (lighting fast) speed. However when using thunderbird it gets very slow, I haven't been able to open the mailbox of 294M.
This is a thunderbird problem, not a Cyrus problem. Thunderbird is NOT an IMAP client. It's a POP3/NNTP reader, that's been taught to badly parrot IMAP. It attempts to download and locally index *all* headers. This means that for large mail stores, it'll take a LONG time to figure out whats going on, and lots and lots of RAM too. And this is all on the Client.

The above logs are only an extract of the output. These messages are going in slow bursts. The imap spool and configdirectory are on a SAN. How can I further debug this?
Your SAN is fine, your client is the problem. Unfortunately since Cyrusoft went under (they made Mulberry) aside from Mutt and Pine I don't really have any suggestions for loading large mailboxes.
