https://speed.pypy.org/ is a neat site but I can't find speed benchmarks for Python 3. I recall Python 3 support being in beta or not as optimized. But I am still interested in the results. 

Also the pypy-dev mailing list link http://codespeak.net/mailman/listinfo/pypy-dev listed at https://speed.pypy.org/about/ is dead. It's not clear to me when the mailing list should be used over the BitBucket issue tracker.
