I am open to others debunking my previous test with other/better tests, but from
where I sit the benefit can be clearly seen. Not just with script times, but
startup time will see a 2-3 fold increase as well. This can be hugely helpful

of times.

I have done heavy testing "living" with Dash. Between my repos I have over 80
Dash scripts, with usage going back to 2015:
