I'm running the linuxCNC in a P8H61-M LX motherboard with a 6i25 mesa card toghether a 7i77 to control a 3 servo motor machine without big latency problems the average is:
Max Jitter servo thread 8840 and base thread 9177 ms. But I always get a very bad result when plug some usb devices like pendrives or loading the VitualBox to run XP.
