We migrated from 3.1.2 to 4.0.3 in June 2001. (caching enabled, fast-updates enabled, two-level mailspool directory hash, +250,000 POP accesses on a typical working day, many users have leave-mail- on-server set) If I remember correctly, server I/O load dropped by two thirds and CPU load by half. We'd be elsewhere if it hadn't been for the benefits offered by Qpopper 4. Eric.
