Profile-guided optimization - The Go Programming Language
In Go, the compiler uses CPU pprof profiles as the input profile, such as from runtime/pprof or net/http/pprof. As of Go 1.22, benchmarks for a representative set of Go programs show that building with PGO improves performance by around 2-14%.
