Why Performance Test? As the name suggests, performance testing is all about testing the speed, reliability, and efficacy of devices, networks, programs, and hardware. In the case of user-interfaces, it may also apply to the ease-of-use or navigability. Regular testing helps determine whether devices are working at peak speed and also utilizing resources optimally. For this reason, the process of performance testing can be a comprehensive one, involving several functions across the area or device that is to be tested for its performance. Performance testing thus, is not limited to a specific function or component, but has to be conducted across systems, at times in conjunction with other functions as well. Performance testing may also refer to testing of human performance. It is easier to understand performance testing in this context: it is not so much about individual components performing; but about the final outcome of all the parts coming together to perform a single task. ...
