What kind of load?  What do you define as "extremely slow?"  And is it slow
only with IMP, or with all mail clients.  What are the machine specs?

1) WU-Imap doesn't scale well with the default mbox format mailbox.  If you
have a very large user base, switch mail stores and/or mailbox formats.  If
you have a small user base then this shouldn't be a real problem.

2) If you set up the folders wrong, you can get terrible performance as
the folder search will search your entire directory, or even the entire
filesystem or system.  So make sure your folder setup is currect in
horde/imp/config/servers.php.

3) Provide more useful so we can make actually useful suggestions.

"TAD (Technology Attachment Disorder) is an unshakable, impractical devotion
to a brand, platform, product line, or programming language. It's relatively
harmless among the rank and file, but when management is afflicted the damage
can be measured in dollars. It's also contagious -- someone with sufficient
political clout can infect an entire organization."
