Not really. When it comes to RTOSes, there is one parameter that
defines the performance, which is the worst case jitter time. However,
this is very specific to the application/test-case. So what can be
done is write RTLinux applications and Linux kernel modules that do
the same job, and compare the worst case jitter times. Of course, one
can completely make a mess of the RT applications, so the comparisons
are not justified unless one is sure that the design is correct.
