Performance testing is a subset of performance engineering, an emerging computer science practice which strives to build performance into the implementation, design and architecture of a system.

Performance testing can serve different purposes.

Performance testing can be performed across the web, and even done in different parts of the country, since it is known that the response times of the internet itself vary regionally.

Performance testing technology employs one or more PCs or Unix servers to act as injectors – each emulating the presence of numbers of users and each running an automated sequence of interactions ( recorded as a script, or as a series of scripts to emulate different types of user interaction ) with the host whose performance is being tested.

Performance testing can be combined with stress testing, in order to see what happens when an acceptable load is exceeded – does the system crash?

Performance testing by Florida Solar Energy Center conclusively proved that the increase in temperature at the hottest part of the day was no more than about 5 degrees F. In fact, this study showed that radiant barrier had the potential to decrease the roof temperature once the sun went down because it was preventing the heat loss through the roof.

Performance is commonly broken into two major categories: in-role ( technical aspects of a job ) and extra-role ( non-technical abilities such as communication skills and being a good team member ).

According to Campbell's Model of The Determinants of Job Performance, job performance is a result of the interaction between declarative knowledge ( knowledge of facts or things ), procedural knowledge ( knowledge of what needs to be done and how to do it ), and motivation ( reflective of an employee's choices regarding whether to expend effort, the level of effort to expend, and whether to persist with the level of effort chosen ).
