Stupid text formatting performance question

Technical Discussion
1

Is there any real performance difference between doing
myStr := strconv.Itoa(42);fmt.Println(myStr)
and
fmt.Println(fmt.Sprintf("%d",42)? That’s it. Simple, stupid question.

I’d guess that Sprintf is slower because it has to parse the format string("%d").

Anyway you can benchmark your code with golang :smiley:
