The ideal values for that parameter vary considerably with the balance between number of cores, number of virtual cores, memory (amount and speed) and disk throughput. If you want to optimize it, you'd need to experiment. But it's not worth it; you can easily spend hours shaving a couple of minutes off of your system build time. > should i stick the -j option in the make.conf? No. It sometimes causes problems with the install targets, and besides, it makes the build output very confusing (so when you have a problem, you always want to run without it). _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
