[Cerowrt-devel] android, sqm-autorate and lte and videoconferencing

[Joel Wirāmu Pauling]

Whilst I understand it's not designed for High Bandwidth uplinks - how does
it scale to 1 to 10Gbit symmetrical (or near symmetrical) uplinks ?

One of the problems i've had with Cake is that it becomes CPU bound beyond
around 3 or 4 gigabit.
