G'day,

I've put more work i= nto a test framework around the qdisc tests, but unfortunately flent doesn'= t work easily with Ubuntu LTS ( https://github=2Ecom/tohojo/flent/issues/232, which I thi= nk is an issue with flent parsing the fping output )=2E

Raw results of x= 2 test runs are here:
Each run:



The code r= epo updated here: https://github=2Ecom/randomizedcoder/cake , with thehttps://github=2Ecom/randomizedcoder/cake/blob/main/README= =2Emd which explains how the test work=2E

Based on the questions on this list= earlier, there is a folder with device information for each of the devices=

For example, the Pi4 an= d the Lichee Pi (risc-v) hardware layout is here:

The switch has also been upgraded to a Cisco 3750x, which I think ba= sed on the "show interface" output has a max queue size of 40 frames=2E&nbs= p; The test process clears the counters before each test and gathers the "s= how interface" output at the end=2E

= I really wish the flent was working, so I'll probably see if I can work out= the parsing=2E

P=2ES=2E: I have a pi400 in use as "desktop" for my oldest kid, this is cl= ose to be actually generally usable, I would guess that changing a potentia= l p500 from the pi400's 4GB to 8 GB together with the other imprivements th= e 5 brings might push it over the threshold into the truly useful category= =2E Which probably means that either a potential pi500 will come late and p= robably with only 4 GB, but let's see how this works out now that the suppl= y situation is less problematic=2E
And I understand that there are other capable ARM based SoCs for homeroute= r/desktop duty, I just happen ot have a soft spot for the raspberry project= ;)
