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. -- Bruce Cran
