> Last time I read C++ performance report, all I could find was some old advice like "use list if you want insertion"™. They didn't mention difficulties in using realloc in vectors. They didn't mention inefficiencies in stl HashMap implementations due to iterator invalidation constraints. They didn't mention exceptions requiring dynamic storage and RTTI. Note that many of these problems are not yet fully solved with move constructors. The TR18015 (Technical Report on C++ Performance) goes into details on most of the above (and much more) and it was written in 2006. The only thing missing is a discussion of hash_map as it wasn't part of the standard yet. |
