To give you a bit of an explanation - I'd like to use
clojure/clojurescript for scripting... I was reading the:
http://blog.brunobonacci.com/2017/08/10/lumo-vs-planck-vs-clojure-vs-pixie/
and got curious how does the 1.9.0 behave when talking about startup times.
(Oh BTW notice that lumo and planck compute wrong results, how lovely :)

It really looks like it is the startup time. Unfortunately:
> start with "java -cp <classpath> ..." to get an apples to apples comparison
makes not much of a difference. Anyway, thank you for the (correctly
computing :-) 1.9.0!
