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.
