So you had at least one option slowing down server.

session.save_handler setting. If you don't know what I am talking about, then
session information is stored in files.

Is ident server working? Are you sure that ident lookups are turned off in imap
server's configuration?

Are you sure that server side sorting is turned on on slow server? Memory issues
 usually happen on php based sorting. How many SquirrelMail installs you have on
slow server?
