I know that it is well-known that tr is faster than m//

Except when it is not.

Quite impressive difference, isn't it?
No. The difference is 1/18982.5th of second which isn't impressive at all. q-: The quotient looks impressive but benchmark has to go to a lot of work to be able to guess at that so you won't see a quotient anything close to that in practice.

Congratulations, you've now prematurely optimized this nano-operation.

I find that the difference is usually more indicative of the practical value of the optmization than the quotient.
