You can use RTAI's latency test located in under install_dir/testsuite/kern/latency or install_dir/testsuite/user/latency. For further information check Section 4.7 of RTAI's User Manual.

  • I know how to run latency test For RTAI but i want to compare with normal linux latency test. – sam_13 Apr 15 '16 at 11:52
  • I don't really get the point of doing that - "Normal" Linux latency can be anything - From 0 to "some time next year" - There is no guarantee whatsoever that what you'd be measuring on a test system could be reproduced on any other system under real-live load, or even on the same system the next day.... – tofro Apr 15 '16 at 14:07
