The well-know bench marking website Phoronix has carried out a benchmark run between Kubuntu 9.04 and PC-BSD 7.1 (20/04/2009)

Earlier this month PC-BSD 7.1 was released, which is based upon the FreeBSD 7.1 stable release, but of course with the extra packages and changes that make PC-BSD an easier to use BSD-based desktop operating system. PC-BSD 7.1 ships with X.Org 7.4 and KDE 4.2.2 installed along with many other packages when using the x86 or x64 DVD installations. Though with the Phoronix Test Suite now having enhanced support for PC-BSD, we decided to see how well PC-BSD 7.1 performs against Kubuntu 9.04.

Both systems perform almost equally (only seconds of difference), but Kubuntu scores more points in this test than PC-BSD.

I’d say that this test is not altogether “fair” as different versions of GCC and X.org have been used. This could easily have quite an impact on the results.

It would be interesting to see if Phoronix did this test again later on this year when FreeBSD 8.0 has come out.
