Do you have simple test programs we could use to regularly measure
the performance of multithreading on different target platforms?

FreeBSD should support scaling via threads, but I've no idea about
actual performance yet.

I've been using FreeBSD/amd64 for about half a year now at home
(due to sudden death of my old hardware) and it's running OK,
except for the occasional suprise after a source upgrade ;-)

I second your feeling of dismay about loss of traditional system
administration conventions... no time to keep up-to-date with
everything.
