Bumped into this today, goes in great detail on how to tweak and tune for good latency:

It's so rare to see a well written article written solely to help others.
Very commonly, articles are written by companies who want you to buy something.

I agree, but pretty good, non the less.
I am adding this one from our forum by Mozmck as i looked for it several times and could not find it, i am thinking this should be in the "computers and hardware" section, not in the "general LinuxCNC questions".
