Google loves fast sites. So how can you speed up your site without spending a lot of cash on a dedicated super fast server. Use caching (pardon the pun)!
Content Management Systems (CMS’s) like WordPress and Joomla are incredibly powerful. Each time someone visits your site, the CMS generates each page from scratch. It can be a lengthy process to build everything you see. First it will process the PHP code which will make numerous calls to your database and finally output HTML for your web browser to display. On some sites this could happen between 20 to 200 times per page! Multiply all that work times hundreds of users and your website can drag to a crawl.
If you enable caching each page is only generated for the first visitor. The caching mechanism then saves the data and serves every subsequent visitor the final result. When a page is added or updated the caching mechanism is triggered and a fresh page will generated for the next visitor, saved and served to all the following visitors. This speeds up WordPress by a huge factor.
Trust me, you want it, your visitors will thank you for using it and Google will be bless you. After testing a variety of caching applications West 4 Communications recommends using Hyper-cache. West 4 Communications engineers can expertly configure your site using Hypercache.
