According to iozone, writing a 256M file to this empty 512M
fs works at

	18247338 bytes/second without SoftUpdates
	16687585 bytes/second with SoftUpdates

The results are repeatable with very little deviations. Reading speed
is about the same regardless of SoftUpdates and is around 13.9Mb/s.

The disk is a 9Gb Cheetah LVD, attached to the LVD outlet of Adaptec's
2940U2W.

Another, identical Cheetah on the same SCSI cable, with another 512M
empty filesystem gives

	18179755 b/s with SoftUpdates
	18315425 b/s without SoftUpdates

Again, reading is not affected, but averages higher at around 18Mb/s.

Are this results what one should expect?
