Read what he writes. Soft updates *did* make a difference - they
shaved ~30% off his worldstone. It's parallelization that doesn't make
a difference in his case, because his CPU and FSB are fast enough that
the I/O system is left completely in the dust. This is a 900 MHz box,
probably with a 100 MHz or 133 MHz FSB, not the old 486DX33 you have
lying in a corner.
