"Since the conclusion of the SMPng project, the focus of SMP development in FreeBSD has shifted from deploying locking infrastructure to careful profiling and optimization of kernel SMP strategies for increased performance on common workloads. FreeBSD 7.0 was the first release to benefit from this optimization work." The status of this work includes
MySQL workload benchmarks and
memory allocator performance in the new FreeBSD 8 branch. Also, here is a recent
presentation showing FreeBSD compared to several other operating systems like NetBSD, DrangonFly, Solaris, and Linux.

Oh well.. I don't see him spreading FUD in there. He clearly says that he doesn't know *BSD and that he thinks those discussions are pointless..
Some examples:
Torvalds: I really don't much like the comparisons. In many ways they aren't even valid, since "better" always ends up depending on "for what?" and "according to what criteria?".
NF: If the BSDs were better technically five years ago, has the playing field leveled since then?
Torvalds: I don't think they were better five years ago (see above), and I don't think the question really makes sense.
NF: Are there parts of BSD today that you would like to see adopted in the kernel?
Torvalds: I certainly don't have any specifics, but that's not saying that I'd be against it. It just means that I don't know anything about BSD technical internals, so I'm the wrong person to ask. Ask somebody who uses both.
I think Linus answers are pretty good actually..
'I claim that Mach people (and apparently FreeBSD) are incompetent idiots. '
Well.. don't put too much into it. He said apparently not certainly
