Yeah, I have basically the same issue.  Even with the database on a 
different spindle, the CPU usage during a mythfilldatabase run is quite 
significant and causes hiccups if I let it run during primetime -- which 
it almost always seemed to pick, left to its own devices.  Renicing 
mythfilldatabase doesn't help because a lot of the CPU usage comes from 
mysql.
