DESCRIPTION
===========
Minimizes payload size (compressing css/js files), minimizes round-trip times
(loads JQuery library from CDN, combines external JavaScript/CSS files).
Inspired by Google Page Speed rules.
BEFORE INSTALL DISABLE ALL OTHER PLUGINS WHICH DOING THE SAME (such as Minify, etc.)
WHAT THIS PLUGIN DO?
====================
Try to apply Google web performance best practices.

WHAT THIS PLUGIN CAN DO?
========================
1. Loads JQuery library from CDN Google server.
2. Minify JavaScript
WARINING! Javascript files minifed by remote service http://marijnhaverbeke.nl/uglifyjs
Your web-server must support sockets or curl library.
UglifyJS is a JavaScript parser / mangler / compressor / beautifier library for NodeJS.
3. Combine external JavaScript
Combined in three groups library, applications and plugins.
Or all in one (see configuration section).
4. Avoid CSS @import
If you have custom theme. You may have such style.css, for example:
@import url('reset.css');
@import url('typography.css');
@import url('menu.css');
@import url('activity.css');
@import url('errors.css');
All these css files will be merge to one.
5. Enable compression
Usually it is server job. Apache/mod_deflate
If your server has deflate_module add in .htaccess file:
SetOutputFilter DEFLATE
If no deflate_module, add following lines in your .htaccess file to enable compression
for CSS and JS files:
ForceType application/x-httpd-php
php_value auto_prepend_file "/absolute/path/to/vanilla/plugins/PageSpeed/gzip.handler.php"
6. Defer loading of JavaScript
