Profile-Guided Optimization (PGO) for Rust applications: Practical Guide

• Performance

Profile-Guided Optimization (PGO) is a compiler optimization technique that helps with optimizing software based on runtime statistics. This optimization is available for a long time in the Rustc compiler. I applied PGO to many kinds of software (compilers, databases, log solutions, CLI tools, and many more), collected a lot of carefully hidden traps on my journey, reviewed many open-source projects, and found multiple PGO integration approaches. In this talk, I want to share with you my experience. LEVEL: Intermediate
