:)  When I see msec, I always wonder whether it is milli or micro. So I
tend to spell them out completely.  It is very easy to mess up.

Personally I like to evaluate RTEMS performance using psim since the
decrementer is actually counting instructions.  That tends to focus
you on removing operations not trying to take advantage of a particular
CPU models characteristics.
