I'm wondering if edge servers with 1Gb NICs are inside the "CAKE stays 
relevant" territory?

My main customer/employer has a gazillion of those, currently reporting

**

*qdisc mq 0: root*

*

qdisc pfifo_fast 0: parent :8 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 
1 1 1

...

*

because their OS is just a tiny bit elderly (;-)). We we're planning to 
roll forward this quarter to centos 8.2, where CAKE is an option.

It strikes me that the self-tuning capacity of CAKE might be valuable 
for a whole /class/ of small rack-mounted machines, but you just 
mentioned the desire for better multi-processor support.

Am I reaching for the moon, or is this something within reach?
