So why is it taking over 40 seconds for all channels on all ports when it takes less than 10 seconds to poll all channels on one device. LabVIEW should be able to run each port in a separate thread.

Getting an exception for this will take ages so after referring to google I found an article on MSDN with the title Windows Services: New Base Classes in .NET Make Writing a Windows Service Easy.
