#44111 I'm testing right now and I must recognise that the result goes beyond my expectations.
In fact the ESP react very fast and it can receive more than 10 little packets / second with unicast UDP.
With multicast, the link is slower so we can achieve around 2 -3 packets / second. The size of the packet I tested is 30 chars.

The nice thing is that this time includes the reply to the sender.

Stay tuned ....

#44133 Very encouraging results.

I'm assuming the multicasting was sending to a specific multicast group of addesses, so the slower times would be consistent with a receiving node needing to process whether its local address is a valid member of the multicast group or not.

Broadcasting to all (address .255) should have less complication, so it would be interesting to know how its timings compare to unicasting and multicasting?
