•Given a call among a unmarried computing device with pace s, or n machines each one with pace s/n, which should still we choose?
•If either the coming expense and repair cost double, will the suggest reaction time remain the same?
•Should structures relatively goal to stability load, or is that this a handy fantasy?
•If a scheduling coverage favors one set of jobs, does it unavoidably harm another jobs, or are those "conservation legislation" being misinterpreted?
•Do grasping, shortest-delay, routing suggestions make experience in a server farm, or is what is stable for the person disastrous for the process as a whole?
