Hi,

I have a question about cake's sparse flow latency.

I've been using cake for a while now.  I use dual flow isolation on my LAN, so I shape my LAN interface.  When I download a game on steam, I have about 11-16 bulk flows.  I use the command: watch -n 1 tc -s qdisc show dev eth1 to see my qdisc stats refreshed every second.  I notice that I will see sparse delays of 13-22 ms often.

Is that normal, and what are common sparse delays I should be seeing under that load?

I have tried using HTB + FQ_Codel, and I don't see the latency spikes I have with cake.

I am using an archer c7 shaped to 60 mbps down 9 mbps up + ECN.

CPU load about 60-80%.

Thank you,

Noah
