I did notice on the graph I looked at, that it was a bit higher - I only 
tested with wget. I was going to repeat properly and if you were still 
higher suggest that you set quantums to mtu, low bursts and set

HTB_HYSTERESIS 0 in net/sched/sch_htb.c.

I also have esfq attached to classes

Hmm I only have 2+default shared by IP - but two more "above".

OK but it won't work for you - I guess. It needs connbytes a hacked IMQ 
and esfq. It's just a test evolved from digriz script really.

I also have half your bandwidth - and it was set at 400kbit for the test.

Andy.
