Performance can be affected by the availability of multiple types of physical and virtual devices. This explains the existence of multiple performance metrics (factors to measure performance). Some popular performance metrics include availability, response time, processing speed, latency, bandwidth, and scalability. These measurement mechanisms are usually directly related to one of the general resources (such as CPU, network throughput and so on) that were listed in the preceding section. We will now look at each of these performance metrics in detail.
Common performance metrics
Availability
If a system is not available at some stage, even if it is only partially unavailable, we will perceive it as bad performance. The availability...
