Since we're on the subject of improving performance I should share one little thing I learned recently. I use Fedora+CCRMA. The Fedora update manager is python based. After disabling the automatic update service I eradicated virtually all xruns. I asked a more knowledgeable friend why this may be and he told me that Python is/can be greedy with resources. YMMV.
