Ok, I've gone through my log files, and it looks like the number of systems downloading SMP kernels is around 4% - 6% of the number of systems downloading GENERIC kernels. That said, I don't think this should be used as a measure of how popular SMP is on FreeBSD systems overall, since people with high-end SMP systems are more likely than average to build their own kernels rather than using those which I distribute and the availability of SMP kernels via FreeBSD Update wasn't very widely advertised. It is probably safe to conclude that _at least_ 5% of FreeBSD systems have more than one processor, but I suspect that the actual value is considerably higher than that. Colin Percival
