Making A Go Program 42% Faster With A One Character Change tl;dr: "If you read the title and thought “well, you were probably just doing something silly beforehand”, you’re right! But what is programming if not an exercise in making silly mistakes? Tracking down silly mistakes is where all the fun is to be had! I’ll also state the usual benchmarking caveat up front: the 42% speedup was measured while running the program on my data on my computer, so take that number with a big old pinch of salt."
