I normally have top set to show loadavg, whatever is on the next
line, a %Cpu line for each core, with a line of '|' after the
percentage, memory, swap, and then the old-style details (running
processes rather than trees of threads).
But I think you are talking about loadavg on your 12 core machine ?
I was seeing loadavgs of 4 or 5 from time to time while rust was
The diference here is that I'm used to individual processes each
going up to 100%, but here the main process is/was running at 400%
(only 4 cores on this machine).
In my seventh decade astride this planet, and as my own cells degrade,
there are some things I cannot do now: skydiving, marathon running,
calculus. I couldn't do them in my 20s either, so no big loss.
