There is a major difference between performing profile-generated optimizations at compile-time based on sample data, and performing it at run-time based on real data. It is one pretty good way in which JITs could beat programs implemented directly in C.

- pbiggar 14y agoThat is the most optimistic statement about profile-directed optimization that I have ever read.
