"unrepresentative" is the main criticism against pybench. PyBench is a suite of micro-benchmarks (almost nano-benchmarks, actually :-)) that don't try to simulate any real-world situation.

PyBench may also be unreliable, because its tests are so static that they could be optimized away by a clever enough (JIT) compiler.

Regards

Antoine.
