Hi there!
I installed RoundCube 0.1 stable a week ago to access my IMAP-mailbox.
In the installation guide I used it said not to enable caching because it might cause some trouble (I can't find that guide right now, but it was in the wiki on roundcube.net).
Unfortunately RoundCube is quite slow when accessing my main IMAP-folder with over 4,000 messages.
So I wonder if that advice (not to use caching) is outdated, or if I still shouldn't use it. I guess caching would speed RoundCube up, right?
I'd love to see where you read that, Arne.
I've got a copy of RoundCube running with its cache going on a connection to Gmail, and it's operating fine.
I see no reason why it could be unsafe or disadvantageous, aside from the fact that if you have many users with huge mailboxes, your database will get bogged down pretty quickly.
