If nothing else convinces you to give it a shot, consider this: _“In Go 1.21, workloads typically get between 2% and 7% CPU usage improvements from enabling PGO.”_ Michael Pratt (The Go Team) And if you fancy _another_ article on the topic, Landon Clipp has [another practical intro to PGO here](https://landontclipp.github.io/blog/2023/08/25/profile-guided-optimizations-in-go/) that provides more of a "user-facing perspective."
