Well, don't know how much gain you'll get, but yo could try the following quickies: <code> import wmi c = wmi.WMI (find_classes=False) for i in c.Win32_ComputerSystem ( ['TotalPhysicalMemory', 'Name'] ): mem = int (i.TotalPhysicalMemory) compnam = i.Name for i in c.Win32_Processor (['Name']): cputype = i.Name </code> If you were going to repeat these often (say, in a loop, which doesn't seem likely given you examples) you might gain a few nanosecs by pulling the attribute lookup outside the loop: <code> import wmi c = wmi.WMI (find_classes=False) ComputerSystem = c.Win32_ComputerSystem Processor = c.Win32_Processor while True: for computer_system in ComputerSystem (...): ... for processor in Processor (...): ... </code> But, as everyone else on this list will tell you, there's no point in optimising unless you know you need to to, and unless you know where :-) That's what modules like timeit profiler are for.
