This page recommends to use libthr instead of libthreads. The results with libthr looks better: " which show that, on a dual core athlon, Linux and FreeBSD are basically equivalent. The real FreeBSD problem is that people say that it does not scale well on more than 4 processors. But, obviously things are becoming better and better, and machines with many processors are still not very common. It has taken a lot of time until Solaris has been optimized to not be a mollasse, and similarly Linux has taken some time before scaling well. -- Michel TALON
