Your first guess is algorithmic complexity of the code: extra nested loops, computations, that sort of stuff. And what would you do to fix the algorithmic complexity? Well, you would profile the code, locate the slow section, identify the reason for the slowness, and rewrite the code to avoid the bottleneck. Rinse and repeat until fast.
