Unless your functions are very slow, you’re going to need a very high-resolution timer. The most accurate one I know is QueryPerformanceCounter. Google it for more info. Try pushing the following into a class, call it CTimer say, then you can make an instance somewhere global and just call .StartCounter and .TimeElapsed Option Explicit Private … Read more
It’s pretty intuitive: A program is CPU bound if it would go faster if the CPU were faster, i.e. it spends the majority of its time simply using the CPU (doing calculations). A program that computes new digits of π will typically be CPU-bound, it’s just crunching numbers. A program is I/O bound if it … Read more
Don Knuth started the literate programming movement because he believed that the most important function of computer code is to communicate the programmer’s intent to a human reader. Any coding practice that makes your code harder to understand in the name of performance is a premature optimization. Certain idioms that were introduced in the name … Read more
