I have a FreeBSD system that I have been playing with. I started out with a 433 and PC-66 memory. Setiathome required around ~54,000 seconds to complete a WU. I replaced the PC-66 memory with PC-100 and a WU required around ~46,000 secs. I then replace the 433a with a 300a and raised the FSB to 100MHz. I'm getting WU's in an average time of 34,000 secs. The ratio of the cmdline on a P-II 400 running Win2000 to FreeBSD on the 433 was ~1.5 WU's to 1. This was a memory limited calculation and showed it. The P-II 400 just did 1.5 times as much as the Celeron did. The Celeron @450 is running cool and is producing WU's at the same rate as a P-III 450. The buildworlds only ran about 10% faster because they are I/O bound. You can save a little time by having /usr/src on one IDE controller and /usr/obj on the other. If you are using IDE drives, the flags option on the wdc? controller can really affect how fast netscape loads. I went from 2-3MB/s to 14.4MB/s on a benchmark by setting my "flags 0xa0ffa0ff" on the HD's.
