Chrome developer tools has a very cool feature to audit a web page and flag issues that by fixing them will provide your web page with better network utilization and performance, the usage is very simple and the results are really cool.

Let’s try it out in the WordPress dashboard page, to do so we will bring up the tools pane by selecting Settings -> Tools -> Developer Tools or by using the hotkeys <Shift>+<Ctrl>+I. Then we will choose the Audits view, in that view we will make sure we choose “Reload Page and Audit on Load”:
