The scheduling latency is variable, but the worst case scheduling
latency and best case scheduling latencies are not, by definition.
Running the latency test under high load for a long time gives you a
good idea of the worst case and best case scheduling latencies. But you
should be sure to try and cover as much as possible of the whole code of
the linux kernel, which is why we use LTP as part of the load we put on
the system.
