Only slightly relevant question, when benchmarking a multi-process job, such as compilation, the timings of a single job-unit vary greatly between runs, as they might be scheduled to a complete different class cores, so comparing stuff like clang's `-ftime-trace` becomes exceedingly difficult.

So the question is, has someone found a way to force macos/terminal session/command invocation to run only on certain types of cores, for benchmarking purposes? I would imagine, command akin to caffeinate, but that would force the qos or available cores on all child processes would be ideal, but so far I haven't found a way to do that.
