Increasing the loops by a factor of 10 I got these times: So far as I understand it i++ is ultimately equivalent to i = i+1; with the exception that if an assignment is occurring on that line then the current value of i would be used and a later instruction would add one to i. Over the past couple of years, Amazon has been leasing planes to build its fleet. Updated the code to include the while loop option, still not seeing anything that looks like a positive significant difference: [TestLoopSpeed.as] Updated with fancy while loop pre-increment action, ++ and -- operators were designed to resemble the assembly code for increment and decrement, but nowadays it shouldn't make much difference with advancement of compilers. The only thing that differs is that the return value of ++i is i+1 whereas the return value of i++ is i. 1-faster.com links to network IP address 184.168.221.35.

Flash will store declared variables as class variables. The inc generates just an inc [i] instruction whereas the addition generates mov ax,[i], inc ax and mov [i],ax instructions. It's worth mentioning that a variable will not hold the same value after each of those operations which means they're not interchangeable without altering the code that uses this variable.
