This will not revolutionate performances alone. We will win between 1 to 4 minutes.
But we win as well:
- it's a step for parallelizing the tests
- new tests are less expensive as they do not create a new jvm: it's a continuous win
- it will allow to push it on dev env while having the same env on dev & on build, and 3 minutes are 10% of small + medium tests execution time.
I will do a few "submit patch" to see if it works well before asking for the real commit.
