Hello internals!
I have noted some strange points about
str_repeat performance. It looks
like the lesser $times argument is, the bigger is execution time (only if
we consider big numbers).
For example, str_repeat('%d ', 12500); is a lot slower than
str_repeat('%d ', 1250000).
First case (slow one):

Second case (fast one):
