I was rather thinking about running the user-space load which
creates high latencies with your own latency test.
But if you are interested in running xeno-test, you should check its
- either by running it with the -h or --help argument
- or by checking its manual page, either on your disk or on xenomai
- or by reading the page where we explain how we do the benchmarks
