We have 10 Gb networking between the Source 5700 and destination 5700 and almost no latency <1 ms. For all practical purposes they might as well be side by side in the datacenter plugged into the same switch.

I have never been able to get the transfer to even 1 Gb. I am replicating a new file system and current transfer is 44712 KB/sec which is .34 Gb/sec

No bandwidth limits have been applied to the interconnect.

What kinds of transfer rates are people seeing over what speed netowork links? to me this seems unreasonable.
