Could it be thrashing swap? Is Horde speaking IMAP to the server, or is it directly checking /var/spool/whatever/? The one thing that jumps out at me below is the amount of memory; it seems conspicuously low. Check 'free'; if you're swapping a lot, double (at least) the amount you've got in the box.
