Applications do not need to be changed/recompiled to be able to run them on a rt-kernel. But, if you want to get the lowest latencies possible, you should consider adapting the application. The RT-kernel is not a magic thing making all applications to behave RT, even if those applications were not designed for it. Bad applications will always be bad, the RT-kernel will not change that. You will get lower latencies if your applications use RT-priorities, but also mlock-ing is required to prevent the application from getting swapped to disk. There is also a relation to the priorities of other RT-threads in the system, and so on.
