This is solved by increasing TCP window size, it doesn't depend very much on MTU.

Larger MTU is better for devices that for instance do per-packet interrupting, like most endsystems probably do. It doesn't increase long-RTT transfer performance per se (unless you have high packetloss because you'll slow-start more efficiently).
