Re: hw.ncpu=1, hw.ncpuonline=1, hw.ncpufound=4

Thank you

I was not aware of the security issues of hw.smt. Fortunately, things
are fast enough without it, and I'm setting up a true multicore AMD
system soon.

On my hypothesis about CPU usage competition, I was using "interrupt"
in the sense that doesn't involve computers. For example, suppose that
I first run something that outputs its processing as it processes, like
nmh scan(1) or playing music with mpv(1). Second, in the middle, I run
something that uses the filesystem a lot, like a borg(1) backup. The
first thing's output will stop for a moment while the second thing runs.

Best salutations,
