I'm sorry to have used the term "useless" since it was not what I meant. In
fact, after profiling the simple draw example, I realized there were a lot of
necessary operations that were not quite visible from my "external" point of
view. I was just thinking "why the hell is it so slow to draw s

Nicolas,
I'm not sure how you've reached your conclusion.
The 21,000 calls to Line2D.draw (i.e. 21 per frame) are easily explained
since each grid line (or tick) is in fact a line.
The 10,000 calls to Tick.draw (i.e. 10 per frame) are because there are
10 tick labels.
likewise for Text.dra
I just did it using the regular python profiler (and a pyglet backend because
glut cannot be easily profiled).
Here are some results for exactly 1000 frames displayed:
> python -m cProfile -s cumulative test_backend_pyglet.py
7723453 function calls (7596399 primitive calls) in 16.583
Have you tried running it in the Python profiler? I find this script
[1] in combination with kcachegrind to be very useful in answering these
kinds of questions.

I've created a fork at: https://github.com/rougier/matplotlib/tree/gl-backend
The name of the backend is glut (it requires OpenGL) and does not display
anything, it only measures fps.
It seems to be stuck at 100fps with the following test script:
import matplotlib
matplotlib.use('glut')
