FreeBSD also supports HT, and is easier to manage to boot. I would
question the gains here since Radiator doesn't use threads
(and I hope it stays this way, I have a boatload of other Perl
complexity/database connectivity issues to deal with such as memory
leaks). RedHat has become too bloated and buggy over the years for
server use. Try Rock Linux, or Linux from Scratch. It doesn't take too
long to customize/strip down Rock Linux. RedHat and friends are too
time-consuming/annoying.
