Do you have a pointer to real world data about the effectiveness of these optimizations? I learned about it (SSO, in std lib which is basically the same) in an article which really made it look as that would make anything in C++ blazing fast. In the codebases I worked, a couple of times, I did measure (what you shoud do before optimizing) and the results where between absolutely negligible to worst when active. But that were 3 data points. Mind you one in a real time database.
