I installed linuxcnc and checked the latency.
It scored 12 million nano second

Not yet, there are things ti disable in BIOS, like hyperthreading, power saving, TPM, sleep states, turbo mode, speed step, etc.
And get the older Wheezy ISO as it uses the RTAI kernel and test with it, should do much better.
Also, repasting the CPU cooler will often make the PC usable.

I wanted to follow your recommendation, entered the bios . Could not find anything related to hyper threading.
I really dont know what I did as there are many settings, but after I reboot, the base thread latency running about less than 20000 ns
coming down from 12 million. Never thought it is possible.
It is better than my other device.
It is difficult to find a computer that is powerful enough and has a parallel port.
I really appreciate your support to the users

That might very well be usable, so start one of the included parallel port configurations and leave it running for a while, see if it shows latency warnings.
