I will run it again and see if it is reproducable

[crepererum]

I would be surprised if there's a notable difference, esp. for this change. Under the hood, it's basically all the same, see

I agree - I just want to be sure

[alamb]

I ran the benchmarks again and see no change. Thus I conclude this PR does not change performance significantly
