week 10: Chapter 8 (performance) 100% complete

Performance is about the management of system resources in the face of particular types of demand to achieve acceptable timing behavior. Performance can be measured in terms of throughput and latency for both interactive and embedded real-time systems, although throughput is usually more important in interactive systems, and latency is more important in embedded systems.

Performance can be improved by reducing demand or by managing resources more appropriately. Reducing demand will have the side effect of reducing fidelity or refusing to service some requests. Managing resources more appropriately can be done through scheduling, replication, or just increasing the resources available.
