Setting this makes your machine more "usable" while waiting for those
Isar builds.

Not set by OE by default. Isn't that something for local tuning?

I know. But we either carry it in all kas files or centrally in the
bitbake.conf. This could also be a default for kas local.conf
creation ... Just wanted to propose it and hear the feedback.

I also think kas could be a better candidate. Performance is the last, but
important goal of Isar, why reduce it by default for new users if more
experienced users can easily do it locally.
With kind regards,
Baurzhan.

If you are not doing anything else on your machine the niceness will
not decrease the performance.

BTW, I never experience major issues with running full load like this in
parallel to editors or browsers. Of course, if you have a time sensitive
application running, multimedia etc., you feel the difference. Then I'm usually
just doing "docker update <build_container> --cpus <maxcpus-X>". And I suspect
"--cpu-shares <share>" will do similar things as this nice level, just never tried.
