FreeBSD 8.0 vs. Ubuntu 9.10 Benchmarks
Starting off with the timed ImageMagick compilation process, FreeBSD 8.0 was able to build this open-source application noticeably faster than on FreeBSD 7.2 (even though both are using GCC 4.2.1), but Ubuntu 9.10 with GCC 4.4.1 took much less time to build ImageMagick.
The LAME MP3 encoding performance between the three operating systems was close, but Ubuntu 9.10 Alpha 6 was marginally in front.
Surprisingly, the best performer with the 7-Zip compression test was the older FreeBSD 7.2 release. FreeBSD 7.2 was about 7% faster than the newer FreeBSD 8.0 code while Ubuntu 9.10 performed at about the same speed as FreeBSD 8.0.
