After spending months carefully building his closed batch data storage system, David comes to see his advisor with the following description and measurements: The MPL for the system is fixed at 19 jobs. David explains that 90% of jobs find the data they need in the cache, and hence their expected response time is only 1 second. However, 10% end up having to go to the database, where their expected response time is 10 seconds. David’s advisor asks one question: “How many jobs do you see on average at the database?” When David answers “5,” his advisor says he needs to go back to the drawing board. What went wrong?
