Could you tell us a little bit more about your system? The stock fedora
kernel should do much better than this without realtime scheduling
unless the system is really loaded down, doing lot's of paging to/from
disk etc. I tend to discourage realtime schuling as it gives the RT app
the ability to completely lock your system if it happens to get into an
infinite loop, and multimedia apps are particularly likely to do this do
to the unpredictable quality of data files and data streams that get
thrown at them.
