Memcached is a distributed memory caching platform, which is used to improve the speed of database-powered websites by caching the queries and the responses between the visitor and the server. To put it in simple terms, anytime a particular page on such a website is requested, the script sends a database query to request the info that should be shown to the visitor. If the latter clicks on a hyperlink to open some other web page, the whole procedure is performed again and this results in a lot of database queries and high server load, even more so if the site has lots of concurrent visitors. Memcached "memorizes" this exchange of information, so in case any of these web pages is opened again, the script no longer has to pull any information from the database, since everything is delivered by the Memcached platform. Thus, the overall load speed of your website will "soar" and you’ll have more satisfied visitors and they will be able to browse your website much faster. At the same time, Memcached updates its cache every time any info in the database is updated, so the site visitors will never wind up seeing outdated data.

Memcached in Shared Website Hosting

The Memcached distributed memory object caching system comes as an optional upgrade with each and every Linux shared website hosting package that we offer and you will be able to begin using it the moment you add it, since the PHP extension that it requires in order to run properly is pre-installed on our leading-edge cloud web hosting platform. You can order the upgrade via the Hepsia Control Panel, which is offered with every shared hosting plan and a new Control Panel section where you can administer Memcached will show up. The upgrade is divided into two parts – the number of instances and the amount of memory, so as to give you more versatility. The first one refers to the number of the Internet sites that can use Memcached, whereas the second one, which is available in increments of 16 MB, determines the total size of the content that the system can cache. A heavy-traffic Internet site with a large-size database may require more memory to take an even bigger advantage of the Memcached caching system, so if you want to upgrade this feature, you will be able to do it at any given point with several clicks of the mouse.
