% XXX fill in these figures
% pystone is almost useless for comparing different versions of Python;
% instead, it excels at predicting relative Python performance on
% different machines.
% So, this section would be more informative if it used other tools
% such as pybench and parrotbench. For a more application oriented
% benchmark, try comparing the timings of test_decimal.py under 2.3
% and 2.4.
The net result of the 2.4 optimizations is that Python 2.4 runs the
pystone benchmark around XX\% faster than Python 2.3 and YY\% faster
than Python 2.2.
