Is there any performance downgrade problem since the Go version was upgraded to 1.22?

Hi, I just noticed that the Go version of this project was upgraded to 1.22.

I have a small question: is there any performance downgrade problem caused by this line?

Sometimes, it will.

Thanks for the hint, it's hard to benchmark this part of the code.

How did you notice this? Using something like codeql?

I found it through sourcegraph code seach.

It is hard to make a pattern to find all such cases, but I still found two (both are mentioned in golang/go#66156).
