Hi, There is a discussion thread on llvm-commits list about a possibility of using custom memory allocators for STL to improve the performance and reduce the memory pressure of STL containers, e.g. std::set. I thought that this discussion may be interesting for a wider audience and therefore I re-post the messages on llvm-dev as well. It would be interesting to hear what others think about -
