I have /usr, /usr/src, and /usr/obj on their own ATA-133 controllers. When I was benchmarking Cray's, the kind of write caching you were doing could double the ouput. You wanted the write to be allowed to wait so that reads had priority. If you are running a corp. data base, data integrity if more important but this is my own machine and I wanted turn around speed on the buildworld. A buildworld on 5.x is about 50% slower than 4-stable. On a single cpu, using -j? actually slowed the build down. I do not use the -j option.
