1. Make sure you have -pipe in /etc/make.conf CFLAGS 2. Mount the partition(s) that carry /usr/src and /usr/obj async. Think carefully before doing this to your /usr if you don't have enough free partitions to isolate just src and obj onto their own mountpoints; a crash could require newfs to fix :) 3. Think carefully before using async mounts. 4. Think real hard about whether or not you want to async mount ... got that fixit floppy handy? ... I ran mw tests using ccd with fast/wide disks across a 3940 on a pro/200 and saw only marginal improvement; async definately is what speeds things up. My -current build machine at the moment is a pro200, 32mb of EDO and one f/w disk on a 3940. With async /usr, CFLAGS -pipe -0, no eBones or secure and NOMANCOMPRESS I was building in about 1:41 yesterday afternoon. hope this helps, -Chris
