From a recent post to -questions:
"Alas, during a recent kernel build, I used the -j2 command line option
in "make" and watched as the scheduler repeatedly assigned two instances
of cc (the most CPU-intensive program) to the same core."
I'm not sure this is something we're really better at, unfortunately: I
know I've watched Windows really grok multi-socket, multi-core
HyperThreaded systems and prefer real cores on the same NUMA node when
running a multi-threaded application, whereas it seems FreeBSD struggles
sometimes.
