It does have a throughput graph available. However, this is based on raw inter-packet spacing, so it'll have line-rate bursts interspersed by very short gaps if Cake experiences any scheduling latency greater than the serialisation delay of one MTU. The best counter to that might be to select a low rate, so that the serialisation delay is 1-2ms or so. It should then be easy to contrast with HTB's behaviour at that same rate. - Jonathan Morton _______________________________________________ Cake mailing list Cake@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cake
