Hello Matthew,
you can use the RTEMS record support to investigate issues like this:
https://docs.rtems.org/branches/master/user/tracing/eventrecording.html#
You can send the events to the host via TCP and then analyse it with Trace
Compass or babeltrace.

Free running counter is only 32khz, so ages in cpu time at 200mhz. There is
a nanosecond IEEE 1588 unit on the network interface
I've identified at least 6 timers going at 10ms, only 1-in-1000 invocations
seem take more than a tick to run,.. they are all started in the same
second but with ra

Yeah, you can't use the clock services from rtems in that case since they
don't have a high
Of course without nanoseconds support in the BSP measuring the timer
callback duration is difficult as most calls will be less than a tick.

Ok,
So first step is to create a wrapper that all timers fire through, then an
array to count the number of invocations per timer_id, after that some per
timer_id time accounting.
Will let you know if its anything outside my application.

Hi,
My application seems to be using around 1/3rd of its total cpu usage in the
'TIME' task,. is this the task created by rtems_timer_initiate_server() ?
What would be the best way to get more information,. are there console
commands that would emit more data, or do i need to instrument my
applic
