Like I > said before, would this money not be better spent on ram and raid? =3D) Hmm, I use FreeBSD 3.x-R on three dual cpu servers (PII/PIII) and my impression is FreeBSD does SMP well. Well, I don't speak of multithreaded applications like data bases (I've no experience here) but on process level SMP FreeBSD seems to do a perfect job. I also did some measurements (http://gwdu60.gwdg.de/pmatmat/pmatmat.html) some time ago which showed good results.
