Enabling JS and CSS minification

When your web page loads in a browser, the browser sends an HTTP request to the web server for the page in the URL. Then, as the HTML is delivered, the browser parses it and looks for additional requests for images, scripts, CSS, and so on. Every time it sees a request for a new element, it sends another HTTP request to the server. In order to decrease the number of additional requests, Liferay has the following ready-to-use mechanisms:

Minifier (compressor) that allows you to compress and minify your JavaScript and CSS files
Merging JavaScript files to reduce the number of HTTP requests using barebone.jsp and everything.jsp
Merging CSS files and images for faster loading
Enabling Gzip compression

minifier.enabled=true
javascript.fast.load=true
theme.css.fast.load=true
theme.images.fast.load=true
layout.template.cache.enabled=true
