I did have a time for buildworld at 266 MHz and a 66 MHz Bus, it was 2 hours and 35 minutes with, the -O -pipe options enabled in make.conf. I just did a make buildworld at the 83.3 MHz Bus Speed, and the PII running at 333 MHz, the time for buildworld, with noatime and async mount options was 68 minutes, installworld was 5 min 16 seconds, a kernel make was 2 min 23 seconds. I only have a regular /usr partition. later Kelley To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
