Robert Muir commented on LUCENE-9165:
-------------------------------------
Patch: as explained again, I think its ok because it uses half of the reported
cores. And no longer are we burning the 3 threads-per-jvm for crazy compiler
stuff, so with these defaults I have much happier fans, temperature sensors,
etc. Utilization is so much lower than before after LUCENE-9160, the artificial
cap just wastes resources. I do all my testing with IDEs and browsers open,
xterms/editors everywhere, youtube playing, and monitoring load, temp sensors,
and fan speeds.
> change generate-defaults.gradle not to cap testsJvms at 4

> Dividing by 2 is still good (hyperthreading is still a thing), but the
> artificial cap of 4 is a bottleneck if the hardware has more available.
