Subject: [LARTC] HTB dequeueing in pairs fixed
Date: Sat, 31 Jan 2004 01:40:03 +0000 [thread overview]
Message-ID: <401B0773.9020005@dsl.pipex.com> (raw)
I posted earlier when I noticed that htb was releasing packets in pairs,
even though my burst/quantums were 1 pkt.
To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c .
This gives a noticable gain in upstream worst case latency, for me with
256kbit/s up I used to see +90 sometimes, now it's +45. For the many who
have 128 up it should limit them to +90 rather than +180.
Andy.
