How to get the most speed out your program?

[TerryRitchie]

Compile the final executable with optimizations enabled. That alone should give a 2x - 4x (probably more) performance uplift.

Custom compilation was a method in QuickBASIC, too. For instance if you didn't send anything to the printer, omit the printer subroutine. I still remember the most common optimization switches I used: OSEX. Gee, I wonder how that one got committed to memory? 

Anyway, could you share an example or Wiki link as to how to accomplish this in QB64?

There's a section in the "Using the IDE" side lesson in the tutorial called "Options Menu: Compiler Settings" that explains the compiler settings:
