Impressive work! Just for the record: """ It’s harder to measure aggregate multi-threaded performance because there aren’t any standard multi-threaded Python benchmarks, but the new interpreter addresses many of the use cases that failed to scale efficiently. """ It's crude, but you can take a look at `ccbench` in the Tools directory.
