Page Optimize
Version: 0.5.7
Description
This plugin supports a few features that may improve the performance of page loading and rendering in the browser:
- Concatenate CSS
- Concatenate JavaScript
- Execution timing of non-critical scripts
- Note: Changing script execution timing can be risky and will not work well for all sites.
Testing
To test features without enabling them for the entire site, you may append query params to a WordPress post or page URL. For example, to test enabling JavaScript concatenation for https://example.com/blog/, you can use the URL https://example.com/blog/?concat-js=1.
Supported query params:
concat-csscontrols CSS concatenation. Values:1for ON and0for OFF.concat-jscontrols JavaScript concatenation. Values:1for ON and0for OFF.load-mode-jscontrols how non-critical JavaScript are loaded. Values: ‘defer’ for deferred, ‘async’ for async loading, any other value indicates the feature should be disabled.
Installation
This plugin uses sensible defaults so it can operate without configuration, but there are a number of constants you may use for a custom configuration.
PAGE_OPTIMIZE_CACHE_DIR
Page Optimize caches concatenated scripts and styles by default, and this constant controls where the cache files are stored. The default directory is cache/page_optimize under your site’s wp-content folder.
To change the cache location, set this constant to the absolute filesystem path of that location.
To disable caching, set this constant to false. Please note that disabling Page Optimize caching may negatively impact performance unless you are caching elsewhere.
PAGE_OPTIMIZE_CSS_MINIFY
Page Optimize has CSS Minification capabilities which are off by default.
If you’re using caching, and not minifying CSS elsewhere, it is recommended to enable it by setting it to true.

Plugin's Concatenate JavaScript Function Interferes with WP Visual Editor
By 
When the plugin's Concatenate JavaScript function is checked, it will interfere with WP's visual editor. Rendering the visual editor invisible. Disabling this function will enable you to use the WP Visual Editor again.

Simple and effective

Without mentioning the need for CDN, Cache, …, Page Optimize (for aggregating CSS) with Jetpack Boost (for deferring JS) gave me the best results for free. It does the job in simple way. I summarize my experience with this plugin and similars on: https://mohamadkarbi.com/why-i-host-with-wordpress/
