	Yoiks! This kind of speed difference usually means something 
	horrible has happened: in the past 6 months, a fair number
	of people have found misbehaving ethernet cards, specifically
	including 3com cards, which had decided to go into full duplex
	on half-duplex hubs, 10baseT to 100baseT hubs, or just fail
	miserably.

	I'd try a test with ftp, to see if it's samba or something
	at a lower level: 

| The test say 2 MB per sec in each direction.. what is this??

	Must be 100baseT on an IDE disk (:-)) I would find 7-900 KB/S
	on  10baseT to be normal (65-80% of theoretical), and might
	hope to see 75% of 100baseT if nothing else is interfering.
