Could be. However, try to get accustomed to the "sysstat" rpm - it's a really useful monitoring tool (among others, it provides both disk subsystem statistics, virtual memory usage and CPU utilization). Have a look at it. It happened to my home system when it was used as: webserver (php+ mysql), mailserver AND... workstation! (Yeah, it had my wife's site on it and it was the only system available at home. :(( ) All on 512 MB RAM... Sysstat proved that when being used as workstation, the system CPUs (Intel HT) would spend between 20% and 75% in "idle" state due to huge swapping. Doubling the memory to 1 GB solved the issue. (ok, it's not serving HTTP and SMTP / IMAP nowadays, but doubling the RAM had a tremendous impact on performance by then...)
