Debian 8.0 Jessie - GNU/Linux vs. GNU/kFreeBSD Benchmarks

Here's our latest benchmark results comparing the performance of Debian Jessie GNU/Linux vs. GNU/kFreeBSD -- the Debian port that uses the FreeBSD kernel rather than Linux.

The Debian GNU/kFreeBSD port is now shipping with the FreeBSD 10.1 kernel by default and aside from that has most of the standard GNU utilities and user-land supported by Debian GNU/Linux. GCC 4.9.1 is the default compiler and UFS is the default file-system for GNU/kFreeBSD.

For some fresh benchmarks of the two Debian variants I ddid benchmarks from a system with an Intel Xeon E5-2687W v3 CPU, MSI X99S SLI PLUS motherboard, 16GB of RAM, 80GB Intel SSD, and Radeon HD 7850 graphics. The same hardware and settings were used throughout testing (the reported CPU frequency difference is just due to GNU/Linux using the Intel P-State driver that reports the turbo frequency rather than the CPU base frequency via sysfs. Debian GNU/kFreeBSD didn't ship with Radeon Gallium3D support and thus the graphics performance wasn't tested for these benchmarks.
