> But I don't see that he has any special insights into VM performance, let alone the low-level intricacies JIT design.
The guy had no insights into language design before creating python.
He also has Mark Shannon, has the entire MS team available on the phone if needed (including the .net team, with stellar JIT), time and a good brain.
> As mentioned elsewhere in the thread he really has egg on his face after denying Python's performance problems for so many years.
He spent 20 years maintaining a project with minimal resources, so you have to make hard choices on what to work with. Perfs were not the objective of Python, and for the majority of the use cases of the time, it didn't matter much.
Now that more important things are sorted out, like unicode handling, and that Python 3 is a smooth running project, he is been given the opportunity and resources to work on the problem, so he does.
Good for us.
Honestly, for me perfs are still NOT a priority, I'd rather him work on bootstraping, but I'm glad and excited that something good will come out of this.
