FreeBSD 8.0 also regressed slightly when it came to compressing a 2GB file using Gzip, but it was just over a one-second difference for this large file. Ubuntu 9.10, however, did the best with a compression time of 21 seconds compared 26~27 seconds for the BSD operating systems.
FreeBSD 8.0 returned to performing in front of FreeBSD 7.2 when it came to compressing a 256MB LZMA file, where it had a nice lead over its predecessor. Still though Ubuntu 9.10 had come out in front.
When it came to ray-tracing with POV-Ray, the run-time was close between FreeBSD 7.2 and FreeBSD 8.0, but Ubuntu's Karmic Koala came out with a slight lead.
