Evaluating RTEMS performances (jitter)

[Pierre FICHEUX]

Hi all,

I'm looking for advice to evaluate RTEMS performance, given that there are
*only* RT tasks
and that an intrusive non-RT task cannot disrupt the system (it's very
different on   Linux/PREEMPT_RT or Linux Xenomai as most of the tasks
a non RT - SCHED_OTHER).

A colleague mentioned writing a "low" priority task consuming CPU time
(such as doing computation) and other higher priority periodic tasks. We
can then measure the influence of the first task on the periodic tasks.

Do you have pointers to existing benchmarks ? (preferably using POSIX).

Thx by advance

I would love to change the world, but they won't give me the source code
