And what about when you're running CAKE in 'unlimited' mode?
I tried this:
# tc qdisc add dev eth0 root cake bandwidth 900mbit
This seems fine from a performance point of view (not that high sirq%,
around 35%) and does seem to limit my upstream traffic correctly. Not sure
it helps though, at these speeds the bufferbloat problem is not that
obvious and easy to test over the Internet :)
