Hi Caduel,

Thanks for your feedback.

I didn't know that UTP was quicker. However, we must guarantee that data gets to its destination in synchronous/correct order: it's a quasi-realtime application...

I understand the non-RTOS issues, e.g. associated jitter, and we have some ways to combat this. All things being equal, do you have any information on the actual timings/latencies involved in using QTcpSocket (or QUdpSocket)?

Thanks, J
