I haven't actually measured it, but based on what the above paper says, I can make some firm predictions:
1: When competing against traffic to the same local host, the performance effects they describe will be present.
2: When competing against traffic to a different local-network host, the performance effects they describe will be attenuated or even entirely absent.
3: They noted one or two cases of observable effects of hash collisions in their tests with FQ-Codel. These will be greatly reduced in prevalence with Cake, due to the set-associative hash function which specifically addresses that phenomenon.
