Note: Please refer to our new article on Toradex Benchmark Tests
Note: As far as I can see from the System Monitor the following benchmark only exercised one single core. This Benchmark was done using BSP V1.x.

The Tegra 2 features two Cortex-A9 MPCore ARMv7-A cores with a VFPv3-D16 FPU but does not implement any Neon extension.
With below compiler switches the pi benchmark (http://wiki.toradex.com/index.php/Colibri_Floating_Point_Unit#Performance_Example) can be run on the target in 80 ms:
