I joined the stream, and was able to ask about the throughput they were = getting with CAKE on their hardware.  This is just for the "Route = 10" rather than their APs, and they reported getting about 2.5Gbps = throughput with CAKE enabled.

Supporting 2.5Gbps is pretty good I think, and should be sufficient to = handle all practical Internet subscriptions that are likely to require = bufferbloat mitigation.  For comparison, on the same call they = claimed about 800Mbps throughput for acting as a WireGuard tunnel = endpoint.
