Can you check how many threads you have on Linux with the same configuration? Is it possible to tell GotoBLAS to use 4 threads? If yes, can you also test that scenario? Also, would it be possible for you to test recent 8-STABLE? Just for the sake of experiment. -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
