It might help if you provide the script you are using to build your tc
queues... I find this more readable than the output from the tc stats.

Hello LARTC community,
I am building a TC policy at home that answers my needs for a small DSL uplink 800kbit:
* High UDP responsiveness for DNS queries and ping (Leaf 1:10 prio 1)
* SSH traffic gets higher priority. I view my camera remotely via ssh tunnel (Leaf 1:20 prio 2)
* Guarantied http(s)/IMAP (Leaf 1:30 prio 3)
* Torrent seeding (Leaf 1:40 prio 4)
* Default (Leaf 1:99 prio 5)
* Gigabit local network (Leaf 1:1000 prio 1000)
The problem is torrent traffic consumes all the bandwidth leaving little room for SSH traffic (<100kbit). See attached picture.
SSH traffic class with higher priority than torrent class should be offered excess bandwidth first, but that is not the case.
The only solution I found is to reduce the torrent ceil value.
Could you help me?
Regards,
Ludovic L.
