Currently, what we do to test RT latencies is to run Thomas Gleixner's
cyclictest
(http://git.kernel.org/?p=linux/kernel/git/tglx/rt-tests.git;a=summary)
as well as hackbench, to see what the maximum latencies we get are.
hallo, can please someone suggest for how long time you are running
cyclictest?
if i run it for about 3 min. i get a feeling that the values will not
change anymore, so is there any recommended time for how long to run it?
another thing i do not know is, if i run cyclictest for lets say 3
minutes, than stop ('ctrl+c') and than start again, i get often
different values. so is it recommended to run it more times and than to
pick up the best/worst cases.
i have done some tests already with rt7,8 and 10 but i am not sure if
the tests make any sense - thats why i would really appreciate some
answers on the both questions.
cheers,
doc
