“As was reported recently, the Debian GNU/kFreeBSD port now has
limited support for handling ZFS file-systems and its stock kernel
has been upgraded against that of FreeBSD 8.1. Due to the upgraded
kernel we ran a quick set of benchmarks to see how the performance
of Debian GNU/kFreeBSD to that of Debian Linux.
“We used the net installations of both Debian GNU/Linux and
Debian GNU/kFreeBSD on 2010-09-09. On the kFreeBSD side we were
using the 8.1-1-amd64 kernel with GCC 4.4.5 and a UFS file-system.
On the Linux side was the 2.6.32-5-amd64 kernel with GCC 4.4.5 and
an EXT4 file-system. The test system was a Lenovo ThinkPad T61
notebook with an Intel Core 2 Duo T9300, 4GB of system memory, a
100GB Hitachi HTS72201 SATA HDD, and NVIDIA Quadro NVS 140M
“Using the Phoronix Test Suite we ran a variety of benchmarks to
compare the Linux and FreeBSD kernel performance under Debian.
These test profiles included 7-Zip compression, Gzip compression,
LZMA compression, GnuPG, POV-Ray, C-Ray, dcraw, MAFFT,
GraphicsMagick, BYTE, Sudokut, Himeno, SQLite, PostMark, and the
Threaded I/O Tester.”
