Hi!

Just playing with that ones...

Richard's measurements:

CPU process switch thread switch Kernel version
Pentium 100 12 12 2.1.109
PPro 180 8 4 2.1.122-pre2
Pentium/MMX 200 4 2 2.1.104

My measurements (not running as root, threads not available):
Pentium/MMX 233 4..6 2.1.121
386??/?? (4.79bogo) 170 2.1.121
486DX2/80 12..20 2.1.119

Hmm, that old 486 is not _that_ bad machine after all.
