Actually he said he ws *downloading*, and so he probably doesn't have=20 control over the incoming stream. Remember that you can only really control outgoing rates properly -=20 incoming streams you control indirectly and all you can do is ignore the=20 sender for a while and hope he stops sending you stuff so quickly... So=20 this is probably your problem - HTB reacts instantly, but the sender=20 keeps sending stuff for perhaps several seconds until you stop answering=20 him and then backs off - there is a reaction lag and there is not much=20 you can do about it really.
