If the caching-mechanism of Roundcube decreases the performance of the application instead of increasing it; it might be a good idea to improve the caching-mechanism! :) I hope to be able to spend some time on it this weekend; any additional information on the implementation and ideas behind Roundcube current or preferred way of caching would be appreciated

Roundcube seems to have some difficulty dealing with large mailboxes (large meaning thousands of messages). It can manage indexing one of these, but if I try to actually show a message in a large mailbox, it basically hangs.
When this happens, the browser just sits there waiting for a reply, and I can do a 'top' on the server and watch the apache process just eat up memory until it finally dies.
It seems that Roundcube is digging through the mail and not releasing memory in some way, which becomes a problem as the mailbox size gets large. At least that's my theory.
Does anyone else observe this? This is with Apache 1.3.34, PHP 5.1.2, MySQL 4.1.18 and Cyrus 2.2.12, running on FreeBSD 4.11p14.
Is your SMTP server on the same box? If so, turn off caching in the config, that helped me out. For record, I have ~1100 messages in my Roundcube folder, and switching from/to this directory seems quick. Oh, and I"m on Freebsd 6.0 with mySQL 4.x, Apache2, Dovecot 0.9
If that doesn't help - what does /var/log/maillog say when this is occuring?
