Those are throughput tests - one sender, one receiver with different
size of the packet being sent/received. CPU usage was determined via
/proc statistics. My analysis says that reduced number of syscalls is
main improvement factor, but different (non-rfc-compliant) congestion
control allows faster start and faster recovery.
