5	This directory contains the RTEMS POSIX Timing Test Suite.
6	The tests in this directory are used to measure the execution
7	time of RTEMS directive and some critical internal functions.
8	The results of these test are useful for comparison of RTEMS
9	performance
10
11	+ between versions of RTEMS
12	+ between different boards
13	+ across different architectures
14
15	These tests attempt to benchmark RTEMS as the user would. They measure
16	the execution time for a directive (under various circumstances)
17	from the time RTEMS is entered until it is executed. Where possible,
18	the time is the average of at least 100 invocations of the directive.
19
20	The accuracy of the times reported by these benchmarks is very dependent
21	on the resolution of the timer being used. It is also important to
22	insure that all sources of hardware interrupts are disabled during
23	execution of the tests. This insures that the directive time reported
24	does not include any interrupt time.
