They all seem to be fairly close in the majority of tests. In the conclusion they write, "In our LAME MP3 encoding test, Ubuntu 8.10 was the fastest followed by FreeBSD 7.1".... One needs to consider, the difference was 2%... Thats hardly anything to get excited about, especially if that difference can be accounted for by how much priority the scheduler gives to a userland app vs what the system is doing etc.... Also, it would have been interesting to see more multithreaded work loads. A lot of the apps they tested seemed to be single threaded, doing one job. ---Mike
