This article benchmarks various Go implementations to maximize throughput when searching a 4GB file, achieving a 66x speedup from 0.75 GB/s to 49 GB/s. It highlights performance bottlenecks across the Go runtime, kernel, and memory hierarchy, while showcasing the new Go 1.26 simd/archsimd package for writing AVX-512 code in pure Go.
Background
The author explores extreme low-level optimization techniques in Go to understand the limits of data processing throughput on modern hardware. This serves as a case study for leveraging new SIMD features introduced in upcoming Go versions.
