could you elaborate?
with *anything* that sends data over a network cable you will have "some
latency", this is due to the laws of physics (and not something
depending on [udpsend] or [netsend]).
it is also totally unclear what you mean with "all ok".

so how did you *measure* the (difference in) latency?

i also wonder, why are you comparing udp-transmission with tcp-transmission?
wouldn't it make more sense to use [tcpsend] and [netsend] (tcp) OR
[udpsend] and [netsend] (udp).
