Performance: checking the fact that the system must perform as what every user expects .So
in every action-response of the system,there are no immediate delays. In case of opening windows
forms, of popping error messages and saving the settings or sessions there is delay much below 2
seconds,In case of opening databases,sorting questions and computing there are no delays and the
operation is performed in less than 2 seconds for opening,sorting,computing > 95% of the files.
Also when connecting to the server the delay is based on the distance of the 2 systems and the
configuration between them so there is high probability that there will be or not a successful
connection in less than 20 seconds.
