Did you collect stats on how much garbage collection actually occurred during the tests? How did it compare to stock CPython?

One of the big flaws in benchmarking early versions of Java of course was that most tests didn't end up invoking the garbage collector - hence showing an artificially good result that could not be observed in real-world usage.
