What's missing is build times with hyperthreading disabled. make buildworld -j10 could easily be faster than -j4 even when hyperthreading is disabled, because of increased disk I/O concurrency. 11:43 to build world is very fast indeed :-) -- Pieter de Goeje _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "freebsd-performance-unsubscr...@freebsd.org"
