You got:
Read		Seconds	KB/S    % of 10Mbit/S
NetWare		100	740.00		66
NT		92	804.35		72
Samba 		105	704.76		63

Write		
to NetWare	98	755.10		67
to NT		83	891.57		80
to Samba	230	321.74		29

Erase 		
NetWare 	2	
NTServer	2	
Samba		5

	I would have expected something closer to 725 KB/S on write,
	1100 KB/S read, (From my wife's Win95 machine).

	I initially thought it was a bsd bug, but Dan O'Connor

	...and you have 2.0.6 and 3.4 	

	You might try playing with socket options: Martin Welk 	
	(mw at freibergnet.de) reports "Reading was quiet quick, 
	but writing to the server (especially many small files)
	was sooo sloooow." He's using
socket options = IPTOS_LOWDELAY TCP_NODELAY SO_SNDBUF=262144
SO_RCVBUF=262144 
	and getting better results.

	Experiment carefully with buffer sizes: performance goes
	back down again if you get too large... see
