Website Performance Testing Tools

Overview

It is important to make sure the website is fast for everybody. We need to test webpages in different countries, browsers, connection speeds etc and check if the pages loads within SLA(Service level agreement).

Performance testing is a type of Non-Functional software testing which ensures that the web application/website will perform as expected under the expected user load. In performance testing, we will test the stability, response time, and page load times of the web application by applying concurrent user load.

Let’s look into some of the website performance testing tools.

Performance Testing Tools

  • Apache JMeter
  • HP LoadRunner
  • NeoLoad

Google PageSpeed Tool
