I am attaching a simpler and hopefully more revealing test, speed_test.py. This test repeatedly draws a full circle at various speeds and prints the time spent. Here is the result:
# python3.1 speed_test.py
0: 0.03
1: 6.61
2: 4.32
3: 3.78
4: 3.23
5: 3.21
6: 2.65
7: 2.72
8: 2.66
9: 2.86
10: 2.67
Note that time decreases as speed changes from 1 to 4 as expected, but then changes unpredictably as speed changes from 5 to 10.
