I use the same setting.

So either I don't try it to not have to reboot the machine (I wanted to
try it), or I try it to see if this is broken on 4.9-RC...

Can you share the pipe specific rules with me? It doesn't behaves here
as I think it should behave and I want to rule out "it sits in front of
the monitor"-problem. I've HZ set to 1000.

My intended ruleset is to have 3 pipes: high, med and low priority. ACKs
and ssh should flow through the high priority pipe, some other data
through the low priority pipe, and all other data through the medium
priority pipe. As soon as I enable this behavior, the data flow for the
low priority data drops down to half or a quarter of the previous
throughput. I wouldn't mind if there's an outgoing ssh or medium
priority data flow, but there isn't, so the throughput of the low
priority data flow should drop down.

Bye,
Alexander.
