[RCU] RoundCube with remote IMAP slow

Dear all,

I'm running a RoundCube installation on a FreeBSD server here, and it's fed by a *remote IMAP server. As recommended in the settings, I set

$rcmail_config['enable_caching'] = true;

but despite this, accessing the mails is *dead slow. It takes at least 5 seconds to access any given folder, and this doesn't seem to change after the folder has been accessed once (and hence cached?). This makes using RoundCube quite inconvenient. I'm quite oblivious as to what could cause such a slow performance, but I'm willing to test and try. Hints, anyone?

Cheers, Nico _______________________________________________ List info: http://lists.roundcube.net/users/ BT/9b404e9e
