What is JavaScript execution time?

The Google Developers website covers this topic in great detail, but in short, if you’re still getting this warning, it means you have too much JavaScript being loaded, parsed, and executed in your pages.

Can Pegasaas Accelerator WP handle this?

If you have Pegasaas Accelerator WP installed, minification and deferral of JavaScript, as is recommended by Google, is already implemented.

Resolve the Root Problem

If you already have Pegasaas Accelerator WP installed, you can try to address the root problem of excessive JavaScript execution time by disabling necessary plugins, as many plugins add multiple JavaScript files which all contribute to the load, parse and execution time of your web page.

A Possible Manual Solution Advanced

You could also attempt to identify any JavaScript files that may not be needed for initial page load.  For example, if there are plugins in your page which handle a click action for a component that is below-the-fold, then you could lazy load these script files.  To lazy load a script, you can add the file name of the JavaScript resource to the Settings > Lazy Loading > Lazy Load Scripts panel.  Any .js file that you add in this panel will not be loaded, parsed, or executed in the page until the user has begun to scroll down through the page.
