8 Client-Side Performance Testing Checklist
According to Yahoo, around 80% of application response time is spent downloading elements such as images, stylesheets, scripts, etc. If you’re worried about the performance of your web application, you need to test and analyze not only with what happens on the server but also with what happens in the browser. Some commercial performance-monitoring solutions already take this into account, allowing performance engineers to see how long it takes for elements to render, and then to execute, on your users’ browsers. There is also no shortage of open-source tools available for you to check and improve the ways in which your client-side programs are executing and working.
