I checked the throughput on my home metwork yesterday evening and the
numbers work out roughly in accordance with what we both were thinking.
They are:

From		To 		Throughput
CPU (MHZ)	CPU (MHz)	(Mbps)
------------------------------------------
600		75		50
600		135		75
600		300		89

If you graph these numbers, they nicely approach 100 Mbps asymptotically.
BTW I measured ~ 89 Mbps bi-directional between the 600 MHz and the 300
MHz machine meaning the switch supports indeed a nearly 200 Mbps
throughput.
