execution time

Question

who has the fastest result?

Answer 1

well saying solely in terms of execution time Python is almost twice faster than the php but in cost of almost twice the memory.

so we can't basically judge as which is the fast, as their are other variables involved like wait for I/O operations , implementation style etc.
