This will use all available cores to run tests, and parallelize by all - suite/class/method. On machines with multiple cores, this will vastly improve test performance. These times are on my M1 MBP with 10 (8P + 2E) cores. They were reported by maven on running mvn verify.
I first ran mvn verify and ignored the time.
Then I ran it thrice without this change, and thrice with this change.
All times in seconds.
