This sounds like an issue with your setup.  This is not an issue with  
IMP per se.

Things that can cause delays include (but are not limited to) slow DNS  
lookups, waiting for session locks, and authentication issues between  
c-client and the IMAP server (if not configured correctly, it might be  
trying to do things like CRAM-MD5 authentication, and only after a  
failure does it fallback to regular LOGINs).  Might want to try  
running something like imapproxy that keeps the IMAP connections open.  
  Depending on the results after using imapproxy, it would indicate  
whether there is an issue at the authentication step.

There is a slight advantage to using imp auth, but that would most  
definitely not account for a 5 second delay.
