Perfectly presented, thank you very much!
My final questin would be about the environment:
> Skylake server, 2 numa nodes, 104 CPUs (HT on)
Is the typical nr_running value the sum of 'NA+AVX', i.e. is it ~256
threads for the 128/128 row for example - or is it 128 parallel tasks?
I.e. showing the approximate CPU thread-load figure column would be very
useful too, where '50%' shows half-loaded, '100%' fully-loaded, '200%'
over-saturated, etc. - for each row?
Thanks,
Ingo
