  Optimization Tips forShared hosting • Use W3 Total Cache plugin for caching page and datas . • Serve all the static contents(JavaScript , CSS files and Images ) from Content Delivery Network. • Use jQuery lazy load plugin to server images if there are many. • Minify and Gzip the CSS and and JavaScript files. • For big number of posts and comment table use MySQL’s logical partition. http://pento.net/2011/04/28/partitioning-the- wordpress-comments-table/

  W3 Total Cache MainFeatures : • Page Caching • Minify • Database Caching • Headers: W3TC manages the HTTP headers (cache-control, expires) • Content Delivery Network (CDN )

  Still problem ……………….. Time to move to VPS or Dedicated Server 

  Recommended Server Configuration •Use Nginx Web Server than Apache • Use Varnish or Squid (Reverse Proxy Servers )for serving static content over Nginx server • Use PHP-FMP (FastCGI Process Manager) • Implement Sphinx search engine or Lucene Search Engine for full text search on database. • As always use CDN  • Use Opcode Cache Engine for W3 Total Cache ( APC recommended)
