PGO = Profile Guided Optimization. It allows the optimizing compiler/linker to figure out for itself exactly what the critical execution path(s) of the program (the code that runs most frequently) is/are by requiring the user to execute the code with this special pgo-instrumentation of the compiled code as many times as required to cover typical use-cases, and optimize the code based around the execution paths taken. Profile guided optimization is a strictly optional step which can be used to improve program performance (potentially) more or better than the generalized optimizer (/Ox compiler option with MSVC) can. Fuck. Posting this is undoing my moderations. Oh well.
