Thanks for your suggestions Erik, I had only been speed testing with
smb. I just did a quick test with wget under cygwin and I'm still
getting around 1.5MB/second, which is about the same as I get with smb.
scp peaked at around 900KB/second, which also seems to suggest the
hardware is only working at 10% capacity.
Can you point me to a man page or something for your suggestion "use
packet filtering statistics" ? Where do I start?
