Hi Ale, With the provided details it's not possible to pinpoint what might be wrong with your setup, but for sure I the performance figures look very poor for such a simple scene.
You don't specify what OS, what hardware and whether you are using a debug or release build. You should do all benchmarking tests with a release build as a debug can distort figures massively.
