SubjectRe: [patch 1/4] - Potential performance bottleneck for Linxu TCP

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.
