I checked that:
10000 runs of nbody.py, time in sec
| classic | new-style | n/c
-----------+---------+-----------+----------
python 2.4 | 2.33 s | 2.89 s | 1.24
python 2.5 | 2.06 s | 2.61 s | 1.27
2.4/2.5 | 1.13 | 1.11 | -
You are right, 2.5 is better than 2.4. But the runtime penalty
for using new-style classes remains.
