Latency on a Lenovo M715q

I am trying to set-up a Probe_Basic configuration on my mill. I have successfully loaded Axis onto a Lenovo  M715q with a AMD a6-8570e r5 processor. I have disabled all of the extra stuff in the bios and have tried different linux adjustments like locking the RT to one specific core and I still get terrible latency reports of around 70000ns. 

Why is probe_basic used on AMD processors only?

Am I missing something? Start looking for a different computer?

I have two of these mini computers for a mill and lathe retrofit. I really like the durable form factor.

Why is probe_basic used on AMD processors only?
It is not only AMD, it runs on Intel and ARM also, just the naming has stuck as AMD64 as AMD was the first to market with a 64 bit processor back in the days.
More info would be helpful, like parallel or or Mesa or Pico setup?
70000 might still be usable to a certain point for parallel port, it should be OK for Mesa, no idea about Pico as i never used them.

Hello Tommy 
I am using the following hardware.

I am re using the MSI servo drives, SEM servo motors and Heidenhain encoders, I plan on adding a A axis later.

Is that base period or servo period?
In the ini file, do not change the value of servo period, it should be 1000000 (1 million).

sorry Tommy I have been side tracked all month. I will change the base back to 1million and give it try.
