I am a newbie and don't yet fully understand the HTB stuff, but have
experimented with others scripts/programs and thought about QOS for
latency - which is what I will be aiming for when my home network is
eventually finished.
With an uplink of 128000 and MTU 1500 then you would expect this behavior
as a 1500 byte packet will take >90ms to get up the wire. Reducing MTU
should help, also quantum/burst should be small enough to release only one
packet - I notice some big quantums in your other mail. I don't know about
cable, but with dsl some MTUs are more efficient than others - which are
best depends on whether your dsl uses pppoa or pppoe etc.
Andy.
