I think that because the touch is telling the server when it is ready to
recieve more packets, variation in packet timing is not mainly under the
control of the server

Variation in network switching latency and jitter is a second-order
effect in a switched network, and will be fairly constant assuming that
the link to the server has adequite bandwidth. IMO variation in the
transmission rate as a result of server-side processing is also likely
to be a second order effect concerning packet timing as this is
controlled by the Touch.

Phil, From the testing I have done, higher CPU utilisation is the
result of streaming WAVs, and this is primarily the overhead of
processing the additional packets. I deduce from this that the NIC has
no TCP offload functions, and the CPU controls all networking
functions.

I suggest that reducing the data volume reduces the CPU load, so
probably best to stay with FLAC.

Alex
