[pypy-dev] pypy performance on fractal terrain generator.

[sean riley]

FYI. Performance comparison of pypy and CPython using a fractal terrain
generator and writing out a png file. Pypy is 6-11x faster on my Ubuntu
Intel system.


For 1024x1024 map:

sriley at xxxy:/data/src/cityserver$ time pypy map.py
real 0m0.656s
user 0m0.596s
sys 0m0.052s

sriley at xxx:/data/src/cityserver$ time python map.py
real 0m4.189s
user 0m4.132s
sys 0m0.044s

For 4096x4096 map:

sriley at xxx:/data/src/cityserver$ time pypy map.py
real 0m6.511s
user 0m6.152s
sys 0m0.328s

sriley at xxx:/data/src/cityserver$ time python map.py
real 1m7.641s
user 1m7.124s
sys 0m0.324s
