Configuration problems are not only prevalent, but also severely impair the reliability of today’s system software. One fundamental reason is the ever-increasing complexity of configuration, reflected by the large number of configuration parameters (“knobs”). With hundreds of knobs, configuring system software to ensure high reliability and performance becomes a daunting, error-prone task.This paper makes a first step in understanding a fundamental question of configuration design: “do users really need so many knobs?”
