Due to your "benchmark"'s simplicity you end up with 10000 string instances in C++ and just four str-s (and a lot of pointers) in Python. What happens if you replace 'string' with 'const char *' in C++ ? (Note that this modification is a bit unfair to Python as it would not detect equal strings in different memory locations) Peter -- http://mail.python.org/mailman/listinfo/python-list
