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
I guess I will be sampling results hourly for comparison.
