@jbf I understand what you worried about now. The developers' intuition may sometimes be wrong. So we need unit tests, regression tests, micro tests and so on to verify our code is right. I agree with you that the evidence should be provided.

I try to write a benchmark test locally now. I will share the result with you later.
