software-efficiency

Making software run faster and use fewer resources has long been treated as a secondary concern once code is functional, but that calculus is shifting. This tag covers AI-assisted and traditional approaches to optimizing existing codebases, including profiling, low-level tuning, and compiler-aware rewrites. The focus is on practical, measurable gains in real systems, and on the growing evidence that mature code often hides substantial untapped performance.

The Cheapest Compute on Earth Is the Compute You're Already Wasting

An AI-driven iteration loop made the Snes9x emulator 61% faster on x86-64 and 52% faster on arm64 in three days for under $30, with every frame and audio sample bit-exact against the original. The argument: the cheapest performance gain is the compute already wasted in mature code.
