It is somewhat likely that you are mis-interpreting the results that you observed. It is hard to imagine a situation in which creating a hash_map takes less time than clear()ing it. Using g++4.0.0, creating a 10,000,000 entry hash_map takes 116 seconds on my machine; clearing via either clear() or swap() with temporary takes 8 seconds. > Now runtime drops significantly, 10 fold less. > What's exactly cause this run time reduction? User error, most likely. If you are convinced that you really see what you claim to see, post a complete compilable test case that demonstrates that.
