Joomla Extension - fwSiteOptimizer plugin

fwSiteOptimizer Plugin is a Joomla! 1.5 plugin that participate in site performance enhancement.

fwSiteOptimizer Plugin can automatically optimize external CSS and JavaScript resources, which can reduce both the size and number of requests made to your website. According to Best Practices for Speeding Up Your Web Site, to build a high performance web site, here are the most important  best practices:

  • Minimize HTTP Requests
  • Add an Expires or a Cache-Control Header
  • Gzip Components

fwSiteoptimizer Plugin can help you achieve the above practice easily.

CSS and JavaScript files can be aggregated and compressed into a single file. These optimizations may reduce server load, bandwidth requirements, and page loading times. Css and JavaScript aggregation can decrease the http requests dramatically for sites built with a lot of those resources.

GZip can compress css and javascript files a lot. The plugin only need to compress the CSS and JavaScript files once, so this can save a lot of CPU times, and give a repeat response.
