    put in another way: i'd like to see the "TCP bytes transferred per CPU
    time spent by the TCP stack" ratio to be maximized in a load-independent
    way (part of which is the sender host too: to not cause unnecessary
    retransmits is important as well). In a high-load scenario this means
    that any measure that purely improves TCP throughput by giving it more
    cycles is not a real improvement. So the focus should be on throttling
    intelligently and without causing extra work on the sender side either -
    not on trying to circumvent throttling measures.
