There has been an effort underway within the Debian
development community to pull the FreeBSD kernel within this
distribution to provide an alternative to using the Linux kernel. In
essence with this Debian GNU/kFreeBSD project you have the standard
Debian package set providing a GNU user-land with a GNU C library, but
the FreeBSD kernel is running underneath. The Debian project has also
been working on Debian GNU/Hurd to effectively do the same thing but
with the GNU Mach microkernel. But unlike Debian GNU/Hurd, with the
release of Debian 6.0 "Squeeze", Debian GNU/kFreeBSD will reach a
release status. With the Debian Squeeze release being just two months
away we have decided to provide the first public set of benchmarks that
compare the Debian GNU/kFreeBSD performance to that of Debian GNU/Linux.
We have tested both the 32-bit and 64-bit builds of Debian with the
Linux and FreeBSD kernels.
