There's a couple things to try to isolate the cause of the delay. First run the Data Client and Data Server examples on the same machine. Then run your LV program and the HT-Basic program on the same pc. Run Data Client and Data Server on the different pc's across the network. By doing these steps, you should be able to determine whether your local TCP/IP configuration, the HT-Basic implementation, or the network is at fault. If it's the network, it could be because of traffic or maybe firewalls you're going through.
