Profile-guided optimization

In computer programming, profile-guided optimization (PGO, sometimes pronounced as pogo^[1]), also known as profile-directed feedback (PDF)^[2] or feedback-directed optimization (FDO),^[3] is the compiler optimization technique of using prior analyses of software artifacts or behaviors ("profiling") to improve the expected runtime performance of the program.
