We do have Riverbed Steelhead appliances at both end. According to calculation, maximum throughput can be attained is ~330KB/sec. With the Riverbed "cold" transfer, we should get ~600KB/sec. But I can only get ~250KB/sec with the Steelhead doing its stuff for 500M file so plenty of time for whatever to kick in. Iperf and netperf show great results though. I guess I will be sampling results hourly for comparison.
I can't think of a worse protocol you could use in this situation. Well maybe if it were layered on top of IPX... You may want to consider alternative proposals for handling file transfer between these two locations. E.g. google docs, office 365, etc. Alternatively something simple like using mounts which are r/w on one side but r/o on the other, and using tools like rsync to mirror the r/w on the local side to the r/o mount on other. Live SMB filesharing is a disaster over large rtt links. Nick
