JoomlaTags Plugin CssJsCompress [for Joomla! 1.5.x]

This is a must have plugin for your Joomla website.  This plugin installs in seconds and can make a world of a difference for the speed of your website.  In my case, my website always seems to be slow, not to mentions the pages with Adobe Flex apps.

CssJsCompress will automatically optimize your CSS, HTML and JavaScript, which will reduce both the size and number of requests made to your website. GZip generated CSS and JavaScript files to about 1/4 of the original size. These optimizations may reduce server load, bandwidth requirements, and page loading times.  What sold me was the option to optimize JavaScript.  Initially this plugin interfered with my Shadowbox plugin, but after switching off the JavaScript option, it made all the difference.
