Webmaster tool (Google Webmaster tools), sitemap.xml.gz is submitted directly as a sitemap. While these benefits are not limited to static content, PHP dynamic pages and other dynamically generated content can be compressed by using the Apache compression module, plus other performance tuning mechanisms and the corresponding server-side caching rules, which can greatly improve the performance of the site. Therefore, for PHP
