dynamicFmtString: use rather fix errors.New than fmt.Errorf("%s"

[catenacyber]

As it is faster

Cf catenacyber/perfsprint#3 (comment)

I don't get it. Can you clarify what exactly you wan to say by posting this link?

Thanks

Sorry for the too harsh description

https://go-critic.com/overview.html#dynamicfmtstring states that fmt.Errorf(msg) gets changed into fmt.Errorf("%s", msg) I propose that it should be changed into errors.New(msg) as it avoids the string interpolation and is faster.

Is this clearer ?
