Whoa, thanks guys for all this feedback! Catching up...
- What is the link speed of the slowest network connection between the
RC server and the IMAP server? What is the round trip packet time between the two, i.e. ping, and how many hops, i.e. traceroute?

- Do you have imapproxy installed on the RC server?
Never heard of that.
- What web server are you using?
- What version of PHP?
- What version of FreeBSD?
http://win.ua.ac.be/~nschloe/other/phpinfo.php
- What are the hardware specs (CPU speed/mem size) of both the RC
server and the IMAP server?
RC server:
- 4 cores, CPU: Intel(R) Xeon(R) CPU E5405 @ 2.00GHz (1999.78-MHz
K8-class CPU)
- 8 GB mem
I'd like to benchmark PHP applications in general, or have some sort of general web application benchmark anyway. Suggestions?
I have no idea about the hardware specs of the IMAP server.
- What IMAP server daemon/version is running on the IMAP server?
It must be one of those Microsoft Server installations -- no idea what version though. Remote benchmark possible?
Cheers, Nico

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?
