Sprite batching performance

Hi. I am working on a sprite batcher in OpenGL. I use OpenGL 3.1 and GLSL #version 110. My batcher has the following features: - it works with 1 single atlas texture - no persistence, meaning you push your whole list of sprites every frame - each sprite can have his own UV on the atlas and his own 3x3 matrix transformation - a camera with his own 4x4 matrix The "no persistence" feature is a choice I made to keep the API very simple. No need to "add" or "remove" the sprites. Just ask to render what you need each frame independantly . Today the batcher can reach 800 sprites at stable 60FPS on a 800x600 window. Running on my laptop: ASUS i7-267M CPU @ 1.80GHz 1.80GHz RAM 4Go GPU Intel(R) HD Graphics Family with 116 ext. Is it good performance ? Note: I plan to add a new method in the batcher in order to render more efficiently large tiled backgrounds.

Yes I need help. I want to find benchmarks on some 2D libraries in openGL. It is more difficult to find than expected. If you have any, you can share.
