Linux shined over FreeBSD with the "3000 Fall" test in the Bullet Physics Engine.
Linux continued to beat FreeBSD in Bullet with the Convex Trimesh test.
There is a lot to gather from these benchmark results that directly compare the "out of the box" performance on Fedora, Debian GNU/Linux, Debian GNU/kFreeBSD, FreeBSD, OpenBSD, and OpenSolaris. 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. OpenBSD 4.6 had not won in any of our 20 operating system benchmarks. However, in this article we are just looking at some areas of the 64-bit OS performance and depending upon the system's configuration, tweaking, compiler changes, and other optimizations these results could certainly shake out quite differently. There are also features in some operating systems that make them more favorable than others depending upon your individual needs.
