Well, it depends really.  Assuming the plugins are OK, it's a system
configuration issue.  70% is quite high system load for realtime things,
if your system isn't very well tuned you will definitely get dropouts
pushing it this hard.

Even with a very well configured ealtime system, going much over 80% is
asking for trouble.
