I’m seeing good latency results for Cake at lower MCS levels (graphs below), in case that wasn’t already known.
Yes - despite its complexity, Cake has always performed well on latency in comparison to other qdiscs.
I gather this time you’re comparing it against the mac80211 fq_codel, rather than a conventional qdisc stack?
Yes, this is on stock LEDE, and I hope to complete results on Chaos Calmer.
I haven’t always seen Cake’s latency numbers lower compared to fq_codel. If I take these two:
FQ-CoDel did better in this case, but it was running on the AP (OM2P-HS, 520 MHz MIPS 74Kc). When run on higher powered Intel routers it basically tied fq_codel:
but then as you lower the bitrate, Cake’s performance on the rrul test seems to get better relative to fq_codel:
I look forward to the throughput shifts being solved, where I see results like this:
This is the only thing so far that would keep me from recommending it for my ISP to test. Otherwise the results from Cake are promising… :)
