Trying to find which is the "fastest" can only be done by identical experiments:
- You write a piece of code in all languages, with the SAME source (input) and objective (output).
- Make this in a repeat loop (for/next) to multiply the length.
- Start a timer at the beginning of the program,
- Stop it when the program has completed its work.
- Get the total time.
- Compare performances with the other languages.
It seems evident to say this, but EACH language has its own fast and slow processes, and finding the "fastest" is really a question of WHAT you are doing!
You also have to take care of each CALL you make:
In PhP, two or three similar functions would give you the same answer, but some take longer to execute (sometimes 20 times longer!) By just using a different function, you can make your code much faster!
