in thread How to deal with Huge data

Do not initialize an variable with my everytime the program enter in a loop. Initialize the variable before the loop and them, inside the loop, once the variable will not be used anymore, just clean up the value it holds. This is faster.

The OP is doing I/O. How could this possibly matter, if it's even true?
