RTEMS Applications Supplement - timing figures for rtems_message_queue_receive

Hi All,


I am confused with the timing figures for rtems_message_queue_receive
given in section 10.11 of the "RTEMS SPARC Applications Supplement".
(Actually, the format is similarly puzzling in the versions of this
document for all CPU architectures that I checked).  - This function
performs a memcpy of the message data to the user provided buffer, which
presumably will be the main driver of the execution time for this
function.  Can anyone clarify?  (e.g. What is the message size assumed
in these timing figures?)
