Memcached is a memory caching platform, which is used to increase the speed of database-driven Internet sites by caching the queries and the replies between the visitor and the server. In simple terms, every time a certain page on such a site is accessed, the script sends a database query to get the information that should be shown to the website visitor. If the latter clicks on a hyperlink to visit another page, the entire process is carried out again and this leads to multiple database calls and excessive server load, especially if the site has lots of concurrent visitors. Memcached "memorizes" this exchange of information, so in case any of these pages is requested again, the script no longer needs to pull any info from the database, since everything is provided by the caching platform. Thus, the overall speed of your website will "soar" and you will enjoy more satisfied visitors and they will be able to browse your website faster. Besides, Memcached "refreshes" its cache when any info in the database is changed, so the site visitors will never see outdated data.

Memcached in Hosting

The Memcached distributed memory object caching system comes as an upgrade with each and every hosting that we are offering and you can start using it the moment you order it, as the PHP extension that it requires in order to perform properly is pre-installed on our leading-edge cloud web hosting platform. You can request the upgrade via the Hepsia Control Panel, which is available with each and every shared hosting plan and a brand-new section where you can administer Memcached will show up. The upgrade is separated into two parts – the instances and the memory, so as to give you more versatility. The first one refers to the number of the Internet sites which can use Memcached, while the second, which comes in increments of 16 MB, defines the total size of the content that the system can cache. A traffic-heavy Internet site with a large-size database may require more memory so as to take an even bigger advantage of Memcached, so if you need to upgrade this feature, you’ll be able to do it at any given point with a few clicks of the mouse.
