Even if I use 
                        import subprocess
                        process = subprocess.Popen(cmd,
                                stdout=subprocess.PIPE,
                                stderr=subprocess.PIPE,
                                shell=True,
                                universal_newlines=True)
                        return process.stdout.read()
difference in times are the same.
