Our rule of thumb for token bucket shapers has been 5-15% so a run
against 900 of 855 or lower might show
codel/pie/fq_codel working better. cake is deficit based, and it's
looking good at 900v890. A way to test
cake's aqm more directly against codel or pie is to use cake in
"flowblind" mode.

thank you for tackling some load! These are some of the fastest speeds
and widest workloads we've ever tried these qdiscs at.

I picked up two 12 core xeons today. I went to get my usual cheap
samsung EVO SSD, got one, saw an optane on sale, got one of those for
the main box. I'm a sucker for latency reductions.

They are way too loud, tho.
