The first thing to suspect when logins take a long time with no tangible 
loading issues (i/o, memory, and CPU all good) is DNS. If your resolver 
is trying to query a non-responsive DNS server or servers but eventually 
hits one that works, login and anything involving email transport will 
be plagued by delays.

So: check /etc/resolv.conf and make sure all listed servers are 
responding to queries.
