Vertex cache optimization

I have written well-known Forsyth algorithm for post vertex cache optimization, ACMR of my mesh have changed form 2.0 to 0.67, but FPS and time for model rendering didn`t change. What can it be?

maybe vertexcount wasn't the bottleneck?

I have two meshes (one index buffer and one vertex buffer for each mesh). Before rendering I optimize them. Then in each frame I have a loop with two iterations in which there is glDrawElements call. I don`t have materials, textures and others. My scene is very simple. Increase of render time must be.
I experimenе this application on three machines with different hardware levels and hardware manufacturers and with different operation systems.

If you have an NVIDIA graphics card, you could profile your application with GLExpert (http://developer.nvidia.com/object/glexpert_home.html). It should help you figure out what the bottlenecks are.

Thanck you! I have not yet installed, but I like the beginning. As soon as the look, I will write.
