From some benchmarks earlier in the year I found that creating a 8MB mfs for /var/tmp shaved 20 minutes off my make world time vs. using -pipe Since we are playing the worldstone game, here is my results but I will admit to cheating and building with NOCLEAN and NOPROFILE Pentium II 300 MHz, 128MB RAM Adaptec 2940UW with TAGGING and SCB Paging enabled 2 x Cheetah 4.5GB Fast & Wide 10,000 rpm Disks /usr/obj Mounted noatime,async /usr/src Mounted noatime,async /var/tmp 8MB mfs filesystem (seems to be big enough) /etc/make.conf - as shipped empty /usr/obj Build: make -DNOCLEAN -DNOPROFILE -j3 buildworld Build time: 55 minutes and 30 seconds (Wow!) >From memory dropping the NOCLEAN and NOPROFILE options clocked in around 1:15, but that was several weeks ago. The exact figures are at home. As another comparison, I did a make release on -current last weekend and it built in just on 2 hrs 30 minutes - a significant improvement over 12 hrs++ on my old P100 system. A releasestone might be a better benchmark as the master CVS repository valules are used for make.conf and it is almost impossible to change what is built (correct me if I am wrong here) If I get time over the weekend, I am going to backup my system and install the softupdate patches followed by the CAM patches to see what improvement they make.
