Pypy speed is compared against Python 2.6, yet it implements Python 2.5 compatibility. Shouldn't Pypy speed be compared to Python 2.5 in this case?

When comparing the performance, we use CPython 2.6 instead of 2.5 because it is nowadays the version of CPython most commonly installed. It is also a bit faster than CPython 2.5, so benchmarking against the older CPython 2.5 would be somehow cheating. Performance is unrelated to the set of Python features available; we are working on a PyPy with Python 2.7 compatibility, but this will not have any serious impact on the performance of PyPy.
