Is it worth rewriting code for JNI?

Question

Java

Hi all!
I have a small OpenGL ES 2.0 mobile toy written in Java. Recently, after adding a large number of objects for which coordinates, matrices, normals, etc. are calculated (on the processor, not the GPU. I need to store this data later), there are small freezes. Of course, I'm not testing on the top-end device, but still.
Will there be any sense from the fact that I will rewrite the mat. functions for calculating normals, multiplying matrices and vectors in C? What will be the increase in the speed of these functions and is it worth it?

Answer 1

Hakito : It won't do you any good. Calls to native methods are much more expensive than normal calls. In addition, Java bytecode is translated into machine code (JIT, ART). It will only get worse. If you rewrite everything - perhaps it will be better.
