I find that seriously doubtful, you're going to have to provide a citation if you want me to swallow that.

The relevant comparison is a single JavaScript function in Firefox looping through a static array and making WebGL calls vs. a C++ function looping through the same array and making OpenGL calls.

If the difference is 5000% or more I will donate $20 to the charity of your choice.
