If you had something appropriate we could add it to the rt-tests suite (which includes cyclictest). Not only would this provide an objective measure, but it could also act as a reference implementation for userspace programmers. See here. git clone git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-tests.git cyclictest is the original program written by Thomas, maintained by Clark Williams now. Most - but not all, of the additional tests are modelled after this program, so you might want to have a look at that if you're not already familiar with it.
