Benchmarking Debian's GNU/kFreeBSD

Debian GNU/kFreeBSD continued to lose ground even for 32 threads of 64MB reads. It's unfortunate that there is not ZFS user-land support for GNU/kFreeBSD, which would have made these results more interesting, or if Debian GNU/Linux switches over to using the EXT4 file-system by default as it is becoming significantly slower as we have shared in a number of articles on the matter of Linux file-system performance.

Running the PostMark benchmark on Debian GNU/Linux completely killed Debian GNU/kFreeBSD in terms of performance. The 64-bit version of Debian GNU/Linux was 5.8x times faster than Debian GNU/kFreeBSD.

With the 3000 fall test inside the Bullet Physics Engine, both kfreebsd-i686 and kfreebsd-amd64 were slower than Debian GNU/Linux, especially when it came to the 64-bit testing.

In the 1000 stack test through the Bullet Physics Engine, Debian GNU/kFreeBSD gained some ground against Debian GNU/Linux and was a hair faster with the 32-bit testing while it still lost in the 64-bit world.
