Well it's related because my program has to be as fast as possible, so in theory I thought that using Python pipes would be better because I can get easily the PID of the first process. But if it's so slow than it's not worth, and I don't think is the Python interpreter because it's more or less constantly many times slower even changing the size of the input.. -- http://mail.python.org/mailman/listinfo/python-list
