Memcached is a content caching system, which is used to accelerate the speed of database-powered sites by caching the queries and the responses between the user and the server. Simply put, anytime a particular page on such a website is visited, the script sends a query to its database to fetch the information that should be shown to the website visitor. In case the latter clicks on a link to open a different page, the entire operation is carried out again and this results in plenty of database calls and excessive load on the server, even more so if the site has a lot of simultaneous visitors. Memcached "memorizes" this exchange of information, so if any of these web pages is requested again, the script no longer needs to pull any data from the database, since everything is delivered by the caching platform. In this way, the overall speed of your website will "soar" and you’ll get more pleased visitors and they will be able to browse your website faster. Additionally, Memcached updates its cache every time any data in the database is edited, so the visitors will never see out-of-date data.

Memcached in Web Hosting

The Memcached object caching system is available as an optional upgrade with every web hosting that we offer and you can start using it the moment you activate it, as the extension that it requires so as to work properly is already available on our cutting-edge cloud platform. You can request the upgrade via 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 divided into two parts – the instances and the system memory, so as to offer you more versatility. The first one shows the number of the sites that can use Memcached, whereas the second, which comes in increments of 16 MB, defines the total size of the content that the system can cache. A regularly visited site with a very large database may require more memory in order to take an even greater advantage of the Memcached caching system, so in case you need to upgrade this service, you’ll be able to do it at any point with a few clicks.
