I have ultra 10 NetBSD-1.6.1_RC1

ex0 at pci2 dev 1 function 0: 3Com 3c905-TX 10/100 Ethernet (rev. 0x0)
ex0: interrupting at ivec 10
ex0: MAC address 00:60:08:92:cf:79

I noticed that performance on this interface are poor compared to hme0.
my hme0 performs at 8MB/s while ex0 (3com 905) performa at 4MB/s

anyone saw this in his own system too?
is the fxp0 driver better?
thanks

Rick
