I thought fast-updates and cache files were only in 4.x, not 3.x -- are you sure about the version you're using, and are you sure it supports these features? The cache files stay around and provide a significant optimization for subsequent mail checks if no new mail arrived since the previous login. That alone can really make a big difference in system load (especially I/O). The Administrator's Guide for 4.x has a section on performance that may be helpful.
