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
syntax:
- either by running it with the -h or --help argument
- or by checking its manual page, either on your disk or on xenomai
website:
https://xenomai.org/documentation/xenomai-3/html/man1/xeno-test/
- or by reading the page where we explain how we do the benchmarks
we publish:
https://xenomai.org/2014/07/benchmarking-with-xeno-test/
