We have now extended that comparison to put many other operating systems in a direct performance comparison to these Debian GNU/Linux and Debian GNU/kFreeBSD snapshots of 6.0 Squeeze to Fedora 12, FreeBSD 7.2, FreeBSD 8.0, OpenBSD 4.6, and OpenSolaris 2009.06. More here
If looking solely at the number of first place wins for each operating system, Fedora 12 and Debian GNU/Linux (2010-01-14) were tied with each having seven wins. Behind the Linux distributions, OpenSolaris 2009.06 and FreeBSD 8.0 were tied with each having two wins. Debian GNU/kFreeBSD and FreeBSD 7.2 each had one win.
