I just can't believe that with all the improvements and new developments in the network world that
someone hasn't come up with a broadband technology that can be run over tin cans and string yet
still have 1-2ms of latency!!!

Seriously though... I can see the latency being a huge issue here. I just did a constant ping and
the latency is varying between 90ms  and 240ms... ouch. I'll continue to do some tweaking. Thank you
all for the great ideas and assistance!

It's all about latency, bandwidth is largely irrelevant as long as you
have broadband on both ends. 100ms is high.

Try dropping MTU on client and server machines and see what happens.
That might improve things, but you will never see good SMB performance
at 100 ms latency. At least what I would consider good, which would be
near LAN performance.
