Measuring and Optimising Low Level Network Performance

The low level network needs to be optimised and tested so that the results from higher level tests are robust.

This is a necessary step for any sort of benchmarking to look into options for future development. It will enable us to go forward and start doing other, higher-level, tests with a good understanding of what aspects of the performance are limited by low level considerations. As such, these tests are timely; without them there will be the possibility of erroneous conclusions being drawn from high level tests. The benefit will be to anyone wishing to conduct such high level tests; and at the architectural level to drawing robust conclusions from such tests in making down-select decisions.
