jME comparison?

I'm wondering if jME has been "put to the test", that is compared against other engines (C++ written), in DirectX or OpenGL.

I'm interested in triangles vs. framerate information, and I'm pretty sure a lot of other people are too.

an extremely difficult test to do, since it depends so much on having the exact equal setup. and should be somewhat complex setup to really show an "average game" setup
