@Derelict:
Not really. It still needs a shaper to avoid over-saturating your links.
Yes, but because the limiter has that nifty feature where it can limit evenly per IP address, it leads me to believe that it doesn't limit the queue.
It should be easy enough to test.
limit the interface and test two clients trying to saturate upload at the same time and monitor ping
remove limit from the interface and instead use the limiter and do the same upload test
My guess is the limiter happens before the queue, which means it limits how quickly the queue fills up. If you want Codel to work, you need to limit how quickly it's drained.
*Entirely a guess based on what features the limiter has
