I think it was an article at "http://www.bsdnews.com/" or some mailing list.
I cannot find the article right now, but there was a comparison between
FreeBSD 5/6 and NetBSD, where NetBSD was found to be faster, and then there
was some disscussion whether this had to do with mutexes. And then someone
wrote that NetBSD did not use mutexes like on FreeBSD and that this made the
system faster. But someone else said that it was extra checking in the kernel
that made FreeBSD perform so bad in this comparison ...
