I hate to be the bringer of bade news.. but I was doing some informal
benchmarks between my K6-3 450 desktop running NetBSD-current and my 486
laptop running FreeBSD 4.2-STABLE and I was suprised to find that the 486
beat the pants off of the desktop in my 'rm -rf' test. The results of my
test are below... anybody know why this is happening?

K6-3:	NetBSD/i386 1.5Q
	AMD K6-3 450MHz, 128MB PC100 RAM, 4028MB HDD (PIO mode 4, DMA mode 2)
486:	FreeBSD/i386 4.2-STABLE
	Intel 486DX/4 75MHz, 16MB RAM, 1160MB HDD (PIO mode ??)
