Expanding the role of Software Tester

A Software Tester’s job is to find bugs in the software  – This was  my thinking  when I entered in the field of the Software Testing.This thinking changed or I can say modified while working on the no of projects.There is much more a Software Tester can do apart from finding bugs in the application. A software tester can often guide a developer throghout the software Development life cycle.
Finding  bugs about speed of the application is not enough.For example- try to understand what can affect the speed of the application.There are so many processes running out simultaneously.Sometimes there is no need to run all the processes at the same time.This is one of the major reason behind slow down of the application.So discussing with developers on this  helped to sort out this type of issues.Storing large files on the server can also reduce application performance.So tester can suggest to reduce the frequency of storing the files the server to enhance the speed of the application.
