Try 6 to 12 simultaneous portbuild jobs, that will beat make -j20 buildworld on any metric (mostly when you are building something as large as KDE). I've done that on P4 1.7GHz / 768MB / 40GB ATA boxes and when a few large (1000+ file) packages are being untarred simultaneously, there frequently becomes a tar(1) or two exiting with a signal 4, or a gcc exiting with a signal 11 before it's done. That's on a July 31 -CURRENT kernel FWIW, and before ~July 1, this never happened. Normally I just cron another run to finish the ones that spontaneously SIG4/SIG11'd, and that finishes the remaining jobs. Currently I'm doing another test build with DISABLE_PSE and DISABLE_PG_G in the kernel to see how that handles. As of yet, there have been exactly *ZERO* SIG4/SIG11's this build. That has never happened since KSE MIII, and I've done at least ten or fifteen full builds since then. :-) Regards, -- wca To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
