So you can read off (+calculate) overall throughput, in both directions. And it looks like your latency under load rises by only about 2ms. That's the sort of thing we're aiming for. Pure codel aims for 5ms, so I take it you're using fq_codel. And... yes (1500 * 8) / 4_000_000 = 0.003 It takes 3ms to transmit a full packet in the slower direction. So when it's busy, ping can be delayed on average by 1.5ms (while the current packet is transmitted). Something like that anyway. On 24/08/16 20:33, techicist@gmail.com wrote: > Thanks for the reply.
