The behavior I find puzzling is how rapidly you lose your measurement flows, basically immediately after you hit slow start on the test, packet loss there occurs and they all die. My guess is you actually have insufficient buffering on the gpon or onc sid= es, which also explains your low latency. >> >> At 8ms of induced extra latency without SQM there doesn't seem to be >> much point in running it on your platform.
