That’s useful information.  I may be able to calibrate that against similar tests on other hardware.

But presumably, if you remove the ingress shaping completely, it can then handle full line rate downstream?  What’s the comparable overhead figure for that?  You see, if we were to use a policer instead of ingress shaping, we’d not only be getting IFB and ingress Diffserv mangling out of the way, but HTB as well.
