I have made a very simple program on a CompactRIO (NI cRIO-9002) device that just listens on a port for a connection and when a connection is established, it sends a text string, closes the connection and starts waiting for a new connection again. I tested this program first on a local area network and it worked fine. The response seemed to be almost instantaneous. I then hocked the unit up on an external network with a static IP address. Now, the same program used more than 10 seconds to respond!
Any ideas what it could be?
Best regards,
