It’s hard to imagine a life without internet in the present age of communication. Internet is being used for just about anything ranging from getting a recipe to finding an address or researching on some topic. With the increase in the number of users on the internet, it has become imperative that the website responds to the user requests, with the latest research indicating that if a website takes more than 2-3 seconds, you start deeming it slow even though it has a lot of graphic content to render. Hence it has become a critical performance test to note the response times of your website even if it is launched on an intranet.

Measuring response times of websites can be done in the following context:

  • Checking the response times with the different system configurations of the web server on which the website is hosted.
  • Compare the response times of websites with different builds.
  • Noting the impact of adding graphical content to the website on the response times of websites.
  • Noting the impact of adding same graphical content in different formats (e.g. split images instead of a single big image).
  • Comparing the query performance for a web request exercising the database for different query implementations

This article discusses about an Add-on from firefox that helps the users to find the response times of your website. It also details on how Python scripts could be used to automate the same.
