So the fact i am getting 75MB/s transfer rate between a file on 2 machines on the network?

Confusing bits with Bytes again.

You aren't getting 75MB/s, you're getting 75Mb/s. This difference between B(tye) and b(it) in this context really matters.
Getting 200Mbps from a set of AV500 adapters (however close they are) is getting into miracle territory. You'd usually expect 50Mbps-ish on a good day.
