According to the promises of the Faster CPython Team, the JIT with a >50% speedup should have happened two years ago.

Everyone knows Python is hard to optimize, that's why Mojo also gave up on generality. These claimed 20-30% speedups, apparently made by one of the chief liars who canceled Tim Peters, are not worth it. Please leave Python alone.

Two years ago was Python 3.11, my real world workloads did see a ~15-20% improvement in performance with that release.

I don't remember the Faster CPython Team claiming JIT with a >50% speedup should have happened two years ago, can you provide a source?

I do remember Mark Shannon proposed an aggressive timeline for improving performance, but I don't remember him attributing it to a JIT, and also the Faster CPython Team didn't exist when that was proposed.

Tim Peters still regularly posts on DPO so calling him "cancelled" is a choice: https://discuss.python.org/u/tim.one/activity.

Also, I really can not think who you would be referring to as part of the Faster CPython Team, of which all the former members I am aware of largely stayed out of the discussions on DPO.
