Most modern distributions have the RTKIT DBus service, which allow programs to request realtime priority. But the restrictions imposed by the RTKIT
DBus service prevent the TooB plugins from running. RTKIT does have configuration options, but the procedure for configuring RTKIT is unusually difficult.
If TooB plugins exceed the limits imposed by RTKIT (or if the RTKIT service doesn't exist), the easiest solution is to grant realtime scheduling permissions to
the current user. In truth, you want to make these changes, since they will increase amount of CPU time available to all audio plugins by 500%! (Just one of the reasons you should not be running pro-audio applications with RTKIT).
