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.
