How a seemingly redundant ‘if’ statement can boost code speed up to fourfold

The author shares a performance trick that involves adding a conditional that appears superfluous. The technique can increase execution speed by as much as four times. It relies on how modern CPUs handle branch prediction and instruction pipelines. By guiding the processor to take a predictable path, the extra if reduces costly mispredictions. The approach works without changing core algorithmic logic. The post includes example code demonstrating the effect. Readers are encouraged to test the pattern in their own projects. The author notes that results may vary depending on hardware and compiler settings.
