Fri Oct 29 00:50:45 EDT 1999 make -f Makefile.parallel -j 20 JPAR=2 -DCLOBBER -DNOPROFILE buildworld make buildworld complete Fri Oct 29 01:30:27 EDT 1999 2384.21 real 2809.03 user 1337.21 sys elapsed 0:39:42 busy 86.95% Ok, so I cheated with -DNOPROFILE and I have a somewhat modified bsd.subdir.mk that parallelizes some subdir builds in the "building everything" phase of the make. This is with a dual 466 Celeron, 128M 66Mhz FSB, no overclocking, Abit BP6. I'm using -pipe in /etc/make.conf and /usr/src, /usr/obj and /tmp are all on a striped vinum volume that resides on 2 IBM 9G 7200RPM SCSI drives with softupdates. I like the price compared to the 4 way Xeon! -- Kevin Street street@iname.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
