Shipping CPU-optimized Rust binaries in container images

In an earlier post about gguf-runner I made a point that kept nagging at me afterwards.

The point was this: prebuilt binaries are compiled for a conservative baseline so they run everywhere, and if you build locally with target-cpu=native instead, the compiler can light up the SIMD instructions your specific CPU supports. On an AMD Ryzen 7 PRO 8700GE that was worth about +20.8% tokens/sec for LLM inference. Real, measurable, free.
