Hi Alian, Is there any specific reason to choose block Size as 1456 ( is it related to IP Pyaload??)
Indeed, this is the largest packet size that fits into one ethernet frame (after adding the various headers)
and slice size between 16 and 1024 in UDPCast ???
Below 16, latency would kill performance (because there is a server-receiver synchronization after each slice). Above 1024, OTOH, there is so little change in performance, that going above would bring very little improvement, and increase memory requirements without good reason (each slice is buffered several times in memory, at various places of the pipeline).
