Also for Preempt-RT you might want a more up-to-date kernel (3.18 is pretty ancient)
They are easy to build

Thanks for advise! I compiled Linux Kernel 4.6.2 with rt patch. Results are better, got max Base thread 36000-40000ns. I think with these timings I can execute linuxcnc and calculate toolpathes on one machine.

Is it possible to compile linux kernel with RTAI for x86_64 platform? I think kernel with RTAI patches will be much more time responsive than Preempt-RT.

It seems to be: www.rtai.org/

Have fun Be prepared to be trying just one more compiler switch at 2am.

Strange. I compiled kernel 4.1.18 with rtai-5.0-test2 patches and I'm getting really high latencies 17000000ns. Something wrong.

Seems too obvious to mention, but are you actually running the new kernel?

There are a number of kernel config options to set to get RTAI to work as well as the patches. Did you do that?
