It is however very odd that the Diffserv mode has any effect= on this at all.=C2=A0 It could be explained if a lot of the traffic is mar= ked CS1, since the Bulk tin has looser AQM parameters.=C2=A0 That suggests = that selecting 'satellite' might help similarly.

I need to check what type of traffic my test generated. Selecting= "satellite" did help though.

Something worth trying would be to alter the failsafe shaper= 's rate of advance.=C2=A0 Currently it has a one-quarter rate, which mi= ght be too restrictive.=C2=A0 Tests at one-half and three-quarters might th= erefore be interesting.=C2=A0 Otherwise, I don't think trying to modify= the way ingress mode works will do the right things.

I am skimming through the code but cannot see where the failsafe sha= per's rate of advance is set at one-quarter rate. Could you point this = out?
