i just ported one of my VVVV modules using a UDP (Network Server) nodes to VL to take advantage of the advanced UDPServer features (in particular the possibility to get the sender's IP address).
it wasn't much of a hassle until i noticed that using the VLnode does not receive quite a lot of the UDP messages (i would guess around a third or more messages don't show up).
changing back to the original VVVV UDP Server node i did not notice any message loss at all using the same configuration.
setup: iPad <-- WIFI --> router <-- LAN --> VVVV
looking inside the VL UDPServer node i tried to change the ThreadSleep time in the async loop to 1ms or even remove it entirely but did not notice any improvement (though i'm not sure if this would have made sense at all because i don't know if the messages get queued up somewhere when the thread is asleep)
did anyone experience something similar? for me this is quite a bummer as having the senders IP automatically with every message would make my life much easier...
