PERFORMANCE TESTING:
Response time of the application from client to server.
(i.e),

* Volume--> More number of users downloading at same
time(eg:Downloading any application or software).
* Load--> Entering 'n' of users at the same time in an
particular application.(eg: G-Mail)

Performance testing is nothing but accuracy of the
application or response of the application. for example the
application is should be executed within 2 minutes as per
the srs so we have to test the application how much time is
taken by giving the response if it is more then expected it
is a bad performance. So we have to find out which area it
is missing
