Hi Kris,

Do you think you'd have a chance to load up Windows Server on the same
machine and compare its MySQL and PostgreSQL to modern Linux, FreeBSD
and Solaris?

That's probably asking a lot, but I'm sure I'm not the only person
interested in seeing how Windows' latest kernels perform for server
roles. I just hope that, in such a benchmark, the userland software
implementation is fair to the platform, and not degenerating to
low-performance APIs from lack of optimisation.

There's a lot of debate about the use of FreeBSD and Linux and others
for servers, and personally I'm just happy to have so much choice
available to optimise per project. But it'd be really great to know
where Windows fits in the performance competition, and it's nice to
have some numbers to point to when arguing that free operating systems
outperform proprietary ones.
