Yes, this is a possibility, and I'll revisit it tonight.  I thought I'd 
looked at the CPU usage during transfer, but I should do so again. It 
still seems strange to me that SSH got slower over Gigabit.  It it had 
just not gotten faster, then the encryption would be the obvious 
culprit, but to get slower...

Unfortunately there seems to be no way to turn off the encryption for 
SSH, which would be the easiest test.

Thanks for the suggestion,
