Jose,

In addition to Joe's suggestions, you may want to check if you were
previously using an IMAP proxy between IMP and your IMAP server.  Is your
IMAP server local/on the same machine as IMP?  Were you using an IMAP proxy
before?

Again, I have similar problems to you but my IMAP server performs badly even
with only a few thousand messages.  Partly because IMP appears to ask for a
lot of detailed information about every message.
