Instead of vertex arrays using vertex buffer objects (VBOs) gained a lot of performance. On my Notebook i got more than twice of the speed. On my nokia N8 it also boosted the speed a lot.
Notebook performance (triangles/s):
- ~34560720 without VBOs
- ~115200720 with VBOs
Running on Intel Core i7 (clocked @ 2.2Ghz) and nVidia Geforce GT 540.
