Dear CAKE experts,

I write for your help in getting CAKE to perform on my router as I understand it should.

I replaced my aging Asus home router with a Ubiquiti Edgerouter 4 specifically so I could take advantage of the port of CAKE to it.

I am in the US, with VDSL2 service provided by AT&T at 100/20. I now have all unfiltered traffic delivered by the AT&T modem to the eth0 port on the router.

My desktop runs Windows. So, to take advantage of flent to quantify CAKE performance, I stood up a Linux Mint VM and ran flent rrul tests before CAKE installation, and after.

The first attached datafile, labeled qdisc pfifo fast, is the performance before CAKE. The other file, called 20/95 ack filtered bridged ptm, is my latest attempt with configuring CAKE flags.

My major issue is with Ingress. Egress seems fine.

For ingress, I see very little difference between performances with and without CAKE. And the overall throughput is far less than 100 mbit.

The queuing disciplines on the router are:

jeremymarks@ubnt:~$ sudo tc qdisc show

qdisc cake 1: dev eth0 root refcnt 2 bandwidth 20Mbit besteffort dual-srchost nat nowash ack-filter split-gso rtt 100.0ms ptm overhead 22 no-sce

qdisc ingress ffff: dev eth0 parent ffff:fff1 ----------------

qdisc pfifo_fast 0: dev imq0 root refcnt 2 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1

qdisc cake 2: dev ifb0 root refcnt 2 bandwidth 95Mbit besteffort dual-dsthost nat nowash ingress ack-filter split-gso rtt 100.0ms ptm overhead 22 no-sce

I must be making a major mistake in configuring CAKE.

I would be grateful for any help or advice in getting this amazing program to work as it should.

Many thanks for any help.

Jeremy
