How to test performance?

[xtuzy]

I always worry SharpConstraintLayout can't be used in real word, because i don't know the performance, test in core is fast, but in ui, it need calculate more things, i don't know how to test it. I only know, when i resize Windows app, flow test like slow.

Goolgle use androidx.constraintlayout , i believe it meet needs. I try to add a framerate label and a androidx.constraintlayout flow test to compare with sharpconstraintlayout at a5ec59b7c03bc54a0143389faee82d13039cdaef, get result:

We can see when resize window of app that run in Windows subsystem for Android, androidx.constraintlayout and sharpconstraintlayout all get low framerate. But when change child, framerate is ok.
