Memcached is a distributed memory caching system, which is used to supercharge the overall performance of database-driven Internet sites by caching the queries and the replies between the user and the server. In simple terms, every time a specific web page on such a site is visited, the script connects to its database to fetch the info that should be shown to the visitor. In case the latter clicks on a hyperlink to visit a different page, the entire procedure is executed again and this results in lots of database queries and excessive server load, especially if the website has a lot of simultaneous visitors. Memcached "memorizes" this exchange of information, so if any of these pages is requested again, the script no longer needs to call any data from the database, since everything is delivered by the Memcached platform. In this way, the overall load speed of your site will "soar" and you will have more happy visitors and they’ll be able to browse your site much faster. Plus, the Memcached platform updates its cache when any data in the database is updated, so the site users will never wind up seeing old content.
Memcached in Website Hosting
The Memcached object caching system comes as an upgrade with each and every website hosting that we’re offering and you can begin using it once you order it, since the PHP extension that it needs so as to run correctly is already present on our cutting-edge cloud web hosting platform. You can order the upgrade from the Hepsia Control Panel, which comes bundled with each shared hosting plan and a new section where you can manage Memcached will show up. The upgrade is subdivided into two parts – the instances and the memory, so as to offer you more freedom. The first one shows the number of the Internet sites that can use Memcached, while the second, which is offered in increments of 16 MB, determines the total size of the content that can be cached by the system. A heavy-traffic Internet site with a large-sized database may require more memory to take an even bigger advantage of Memcached, so if you need to upgrade this service, you’ll be able to do it at any point with a couple of mouse clicks.
