Graphic Exploration of Jruby tuning in ruby-processing

The esfera sketch in vanilla processing is in the demo (performance category) and has proved to an interesting test case for various perfomance tune-ups in jruby. For this sketch the rolling fps is a good measure of performance.

 java_args.txt

None
Args 1. -XX:+TieredCompilation XX:CompileCommand=dontinline,org.jruby.runtime.invokedynamic.InvokeDynamicSupport::invocationFallback
Args 2. -XX:+TieredCompilation -XX:TieredStopAtLevel=1 XX:CompileCommand=dontinline,org.jruby.runtime.invokedynamic.InvokeDynamicSupport::invocationFallback

F.P.S esfera

No Args	Args 1	Args 2
5.4547	5.17617	4.70084
4.26695	3.71662	2.90269
3.85179	3.22197	2.30053
3.769622	3.105720	2.077115
3.769622	3.122121	2.022429
3.756052	3.340643	1.940190
4.849481	3.122121	1.953019
5.173814	3.34064

Thereafter no args stabilized at ca 5.4 fps whereas "Args 1" stabilized at ca 5.7 fps. So compilation Tiered compilation beyond level 1 gives best performance, eventually.
