i read today post performance improvement in c# , java. i still stuck on one: 19. not overuse instance variables performance can improved using local variables. code in example 1 execute faster code in example 2. example1: public void loop() { int j = 0; ( int = 0; i<250000;i++){ j = j + 1; } } example 2: int i; public void loop() { int j = 0; (i = 0; i<250000;i++){ j = j + 1; } } indeed, not understand why should faster instantiate memory , release every time call loop function done when simple access field. it's pure curiosity, i'm not trying put variable 'i' in class' scope :p true that's faster use local variables? or maybe in case? stack faster heap. void f() { int x = 123; // <- located in stack } int x; // <- located in heap void f() { x = 123 } do not forget the principle of locality data . local data should better cached in cpu cache. if data close, loaded ...
