My buildworld on a dual 866 coppermine system went from 42 minutes to 29 minutes. The other side effect was the -j8 parameter finally did something. Before that anything from -j2 on, actually made the buildworld run longer. I think the cpu's were starved for I/O. The system is built around 3-ATA-100 Maxtor 30GB HD's. The motherboard is a VP6 and each HD is on its own controller. Using raid-0 also slowed the compile down.
