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).
