PiDiCNC Control System

Are you tried to compare with common pc?

That is a older beter quality common PC with ATI integrated graphic card.
I will do the same test on a Asus P5B Deluxe with core2quad tonight to see if it makes any difference, as for software they both run LinuxMint 18.1 , HP with 32bit RTAI and Asus with 64bit RT-Preempt.
Will also check how it does on an i5 2.53GHz dual core DELL laptop with Intel AND Nvidia graphic cards running 64bit Mint 17.3.
I can also try Ubuntu 10.04 and Debian Wheezy, but i doubt it makes any diference.
Regards,
Tom

What is the sense of this testing?
I am very grateful for your effort, but is it comparable? x86 vs arm. I tried to ask on other thread:
forum.linuxcnc.org/18-computer/20514-emc...spberry-pi?start=290

Just to try to get more info about why it slows down so much after a certain line count, it should not as 150.000 lines of code are a bit over 2 MB , so should pose no such problem.

Aha, ok
Adding video to collection, it is atom eee 901 netbook.

Response of system is ok

That is the same gcode file running on an Atom @600MHz ?????
Well that warants a bit more testing for sure. Stay tuned.
