▶  Boosting Performance of Go Apps with Optimizations — Three members of the Go team gave a talk at last week’s Google I/O about a topic we’ve covered a lot lately – using Go 1.20+’s profile-guided optimization (PGO) to essentially make your programs faster for free. The first ten minutes are an introduction to Go, but the meat starts about ten minutes in. This is a great way to learn about how PGO and some other Go compiler optimizations work, rather than merely their end result.
