IW10 would always speed-up TCP connections during their slow-start phase (initially) but whether that would be noticeable in the context of how much data will be transmitted overall is another question.
IW10 is especially useful for short-lived TCP connections such as those opened by web browsers to load a web page. There are negligible benefits for long-lived connections transmitting a lot of data, such as transferring a big file using HTTP or FTP.
In your case the bandwidth is not a factor to consider. It's the latency that's important. Do a
ping and check your round-trip time for the link, it would probably be 1ms or less. If so - there won't be any noticeable benefit.
In general it depends on what you would use those TCP connections for.
If you are trying to achieve some form of "real-time" communication between the two hosts and you will be sending more than a couple kilobytes of data (even though the connection enjoys high bandwidth and low latency) - a couple of milliseconds may count.
