The part that interests me about this one is not that I necessarily want to run a faster Tornado server, but that I have often been wondering how much speedup I can get from switching e.g. Python to PyPy in general. Granted, it generally makes sense to do your own benchmarking for a particular application, but its also nice to see other people's results like these from time to time, especially against a rapidly evolving project like PyPy.
