depending on your load, there should or should not be some considerable

scenario 1:
web server is on same switch (LAN) as IMAP server --  you should not have
any problem with this even if you have 100 simultaneous users on the web
front of the setup.

scenario 2:
web server is located at a remote location -- roundcube settings permits you
to cache the messages of mailbox content. of course this may have some
payload on the web server, but speeds up RC's loading


// enable caching of messages and mailbox data in the local database.
// this is recommended if the IMAP server does not run on the same machine
$rcmail_config['enable_caching'] = TRUE;

// lifetime of message cache
// possible units: s, m, h, d, w
$rcmail_config['message_cache_lifetime'] = '10d';


having RC run on the IMAP server is also not a bad idea, but when you cant
do that....the above two may help you out. test each to your specific

Of course, you might discount this possibility, but remember that one in
a million chances happen 99% of the time.
