  What you describe as "only" 50% cpu, I am guessing is actually the process
hogging 100% cpu on one core of a dual core machine?  i.e. your problem isn't
underutilisation, it's something running away.  Did you build PRC tools
yourself from source?  Have you asked if they've seen anything like this on
the PRC mailing list?

    cheers,
