FPS performances in jme, jme2 and jme3

Hello everyone,

I made a software to load and display objects (obj then converted in jme format) using jme1.0 .

There are differences between jme1.0 and jme2.0 in performances (fps)?

Replacing the core of my application with jme2, there is an improvement?

And jme3, goes faster?

Thanks to all
