Uses of Doing Performance testing

IRCTC is an application of Rail way Dep (organization) and Central govt is the client. If we want to build an application, organization required

--Developers

-- Administrators( DB and Application server administrator).

--Network administrators and

--Architects  majorly.

Finally end users(me,you ...etc) are using the applications. Here client( is earning the money because of using the application (IRCTC).

If application is opening after 20 min , no end user will use the application.This problem will solved by doing Performance testing before releasing the application to the product.This is main use of doing performance testing.

Other reasons are:

1. Finding development issues like
       a.  Memory leaks

       b.  Synchronization points

       c. Slow queries ....etc.


2.Administrator issues like

       a. High CPU Utilization

       b. High Memory Utilization

       c.  Connection pool issues

       d.  Socket issues and ...etc.


3. Architecture issues like

      a. Poor db design

      b.Poor software identifications .. etc.
