I have managed to connect via OPC UA on node-red, however I am testing with uaExpert OPC UA, and I see that communication is not very fast. This is normal?  
Sending data from UaExperte OPC UA to the server mounted on node red, is OK. But when I write in node red the reading in uaExpert has a delay time.
