Oh dear. The problem with all those webmail programs is that they
are stateless - every time you click on a button or link on
th webinterface, the new page will connect _again_ to your
IMAP or POP3 server, the server will read and parse _all_ messages (and
copy the mailbox around a few times as well if you are unlucky) and then
execute just one or two commands and exit again.
That, by far, will be your biggest bottleneck.
I recommend a system where the webmail backend directly uses the
filesystem instead of IMAP or POP3 like IMP does.
Failing that you need to write a proxy for IMAP or POP3 that caches
the connection for the session.
