Restarting 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.
