An interesting article I found over at Balance Through Extremism. Apparently RedHat has had a long time bug in the bless/overload function of Perl. It causes massive Disk IO usage for no apparent reason.
In short, if you are using the official Perl RPMs from RedHat on RHEL, CentOS, or Fedora, you are likely experiencing a major performance bug. The simple solution is to roll your own.
