Note that -j32 is much more than the system can paralleize. I start getting dimishing returns past -j4, even on dual proc systems. When you hit the rescue build you will be SORRY :) If you want to do load tests, launch multiple parallel buildworlds with differing MAKEOBJDIRPREFIX. -- Doug White | FreeBSD: The Power to Serve dwhite_at_gumbysoft.com | www.FreeBSD.orgReceived on Mon Dec 08 2003 - 11:51:10 UTC
