5This directory contains the RTEMS Classic API Timing Test Suite.
6The tests in this directory are used to measure the execution
7time of RTEMS directive and some critical internal functions.
8The results of these test are useful for comparison of RTEMS
9performance

11+ between versions of RTEMS
12+ between different boards
13+ across different architectures

15These tests attempt to benchmark RTEMS as the user would.  They measure
16the execution time for a directive (under various circumstances)
17from the time RTEMS is entered until it is executed.  Where possible,
18the time is the average of at least 100 invocations of the directive.

20The accuracy of the times reported by these benchmarks is very dependent
21on the resolution of the timer being used.  It is also important to
22insure that all sources of hardware interrupts are disabled during
23execution of the tests.  This insures that the directive time reported
24does not include any interrupt time.
