CONFIG_XENO_OPT_STATS is on which can degrade the performance slightly.
Try to turn this off. I would be interested in the difference on your
boxes (a few micros should be noticeable on the slower one).
I don't know if RTAI has comparable accounting. If yes, check if it's
off as well to keep the conditions fair. I guess CONFIG_REGPARM is not
enabled for RTAI then (LXRT should break, right?).
