My point in posting that particular misc@ post because it found that
tbr is the problem. If you already fiddled with qlimit, it might be
affecting tbr size.

That post is most likely the hotplug PCI-Express ppb problem,
I would expect that particular user's problem to be improved by
changes to interrupt handling in -current. (and to head off the
next question, these changes are not suitable to be backported
to stable.)

Can someone recommend what the qlimit and tbr should be when throttling
a connection to just under 100 megabits?
One of my concerns is we have an OpenVPN running with UDP. Lots of
dropped packets would be rather catastrophic for it.
Thanks,
Tom

I had set up ALTQ on a 4.9 firewall box as a box in our network needed
its sending throttled, but I noticed that while the firewall was
throttling this machine in question, ALL connections going through the
machine were adversely affected and slow. Interactive SSH sessions had
sometimes 1-2 seconds
