+% 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.
