performance boost...

This one took me by surprise, so I have to share. I was consulting at
company who used a Linux cluster to deliver internal mailings (they
have roughly 30,000 employees across the US - which was too much for a
Microsoft Exchange distribution list to handle). The cluster nodes ran
some perl code which effectively called a "performance-tuned" sendmail.
Delivery throughput was around 17 messages per second.
After weeks of arguing I finally got the okay to upgrade one of the
nodes to FreeBSD. The result was that after the next mailing, the
FreeBSD box had a delivery throughput of 29.7 messages per second. Same
hardware, same perl code, same sendmail. Something as simple as
switching from RedHat linux to FreeBSD almost doubled performance.
The best part of course is the satisfaction I now get from rubbing it
in to all the Solaris and Linux admins I work with!
