A random idea about speeding up tests: I've noticed that when tests are starting, all the cores are loaded at 100%, but after some time less and less cores are loaded (see the screenshot). And at the end, only about 1 core or 2 cores are working.

If we make all cores work during the whole testing, I guess the tests will take less time

You can use test infrastructure from :compiler:tests-common-new. It uses native JUnit 5 parallelization which loads all cores for whole run
