On: Python performance: it’s not just the interpreter

Both `-O` and `-C opt-level=3`. I'm guessing this is one of those high throughput scenarios where having a GC is quicker because it's able to defer deallocation until the end of the program.

-O is opt level 2, incidentally.

Yeah, I think you’re right. Very interesting!
