> Results of the CPython benchmark suite. Reference = default branch at rev 496e094f4734, patched: fastcall fork at rev 2b4b7def2949. Oh, I forgot to mention that I modified perf.py to run each benchmark using 10 fresh processes to test multiple random seeds for the randomized hash function, instead of testing a fixed seed (PYTHONHASHSEED=1). This change should reduce the noise in the benchmark results. I ran the benchmark suite using --rigorous. I will open a new issue later for my perf.py change.
