Is Python or C++ better for OpenCV?

Python is significantly slower than C++ with opencv, even for trivial programs. The most simple example I could think of was to display the output of a webcam on-screen and display the number of frames per second. With python, I achieved 50FPS (on an Intel atom). With C++, I got 65FPS, an increase of 25\%.
