The process is running (alone, no > other processes there) on one CPU of an i5 quad core (using 3.13.0-35 > ubuntu 14.04) The expected behavior is "in general" only achiveable with patched kernels. The RT-patches are available here: https://www.kernel.org/pub/linux/kernel/projects/rt/ (Notice availability only for even kernel numbers.) So please get first of all a kernel working suited for "real realtime". This step should be quite simple :-) Good luck!
