Read the article. It's fairly clearly stated that the numbers are skewed
based on benchmarking on completely different OS's, which means completely
different setups, installs, etc.

Ask Joel. His email's posted right there. (er... see his email, see my
email. I know the guy, he's on the up and up... he's not a MS patsy, if
anything, he's a VMS kind of guy.)

The machine may have had full firewalling on, inspecting each packet...
this would mean that each network transaction would be slower, but internal
operations would be as fast as normal. The RedHat box may have had a generic
kernel, weighed down with all sorts of unneeded overhead. The results may
have been the product of openldap's UI, being command line, and thus not
easy to properly configure. The machine may have been running other services
that the NT boxes weren't running.

There's lots of possibilities, which is why it's not part of the main test.
