The problems of achieving satisfactory levels of system performance and reliability are amongst the most difficult that operating system designers and implementers have to face. This is particularly the case with generic operating systems, i.e., systems intended for use in many different versions, in a wide variety of different environments. The present paper attempts to explore the reasons for these difficulties, and to discuss the interplay between performance and reliability, and, in particular, the problems of achieving high reliability in the presence of hardware failures and software errors.
