Then maybe it does not work as expected. Could you elaborate on:

- the figures reported by latency
- whether you enabled debug (--enable-debug) when building the user libs
and programs?
- did you run the autotuner to calibrate the core clock?

You may also want to make sure that debug options like
XENO_OPT_DEBUG_LOCKING are disabled, vanilla kernel debug options
likewise (DEBUG_LIST, IPIPE_TRACE and so on).

That one is a known pending issues with the smoke tests exercising the
some Xenomai debug features, but won't affect the measurement performed
by the "latency" program.
