How to test real-time performance of linuxCNC RTAI?

How to do the kernel latency, switch, and preempt tests?
Or other real-time performance tests?

I have installed the linuxCNC with RTAI.
I also ran the ''Latency Test" given by LinuxCNC.

Thank you.

I found the following:
github.com/relacs/makertai

But It seems that this demo is for Linux with RTAI ?
I am a beginner.

For general Linuxcnc use, the boys have put a of of work into, if your machine passes the latency test you are good to go. From memory there should be some scripts in /usr/src/rtai/"your kernel version" that you can run.

If you want to learn more about RTAI this link should be of help: www.rtai.org/

The github link you gave looks like it is for building a testing a "generic" RTAI kernel.

Tools included with LinuxCNC:
latency-histogram
latency-test
latency-plot

Excuse me, are you using the source code to compile and install RTAI which version of RTAI do you use? Can you give me a copy of your compilation instructions. Thank you

Our team failed to install RTAI in debian linux.
Then, we installed linuxCNC-debian with the RTAI in our controller.
Thanks
