I am currently doing some work on the comparative performance of UDP and
TCP on a RedHat Linux platform.

In particular I have figures for both protocols that measure the CPU usage
for the transmission of data at a fixed bandwidth using varying packet
sizes. (So these are plotted on a graph where the y axis is "CPU usage" and
the x axis is "packet size".)

The results seem to show that TCP has a significantly higher CPU usage than
UDP for the
same bandwidth. This is what I expected.

However, I have seen at least one reputable study that seemed to demonstrate
that the CPU usage was similar for both protocols.

Does anyone have any further evidence to back up either view?

Many thanks

Steve
