Memcached is a data caching platform, which is used to improve the overall performance of database-powered sites by caching the queries and the responses between the visitor and the server. In simple terms, every time a given page on such a website is accessed, the script calls its database to get the information that should be shown to the website visitor. In case the latter clicks a hyperlink to visit another web page, the whole procedure is repeated and this leads to lots of database queries and excessive load on the server, especially if the website has lots of simultaneous visitors. Memcached "memorizes" this exchange of information, so in case any of these web pages is accessed again, the script no longer needs to fetch any content from the database, as everything is delivered by the Memcached platform. Thus, the overall load speed of your website will increase and you will get more satisfied visitors and they will be able to navigate through your site much faster. At the same time, Memcached updates its cache if any content in the database is modified, so the website visitors will never wind up seeing old data.
Memcached in Shared Web Hosting
Memcached is available as an upgrade with every Linux shared web hosting offered by us and you can begin using it the moment you add it, since the PHP extension that it requires in order to function properly is already available on our innovative cloud hosting platform. You can order the upgrade through the Hepsia hosting Control Panel, which is available with every web hosting plan and a new Control Panel section where you can administer Memcached will show up. The upgrade is subdivided into two parts – the number of instances and the memory, so as to give you more freedom. The first one refers to the number of the websites that can use Memcached, while the second, which is available in increments of 16 megabytes, defines the total size of the content that can be cached by the system. A traffic-intensive Internet site with a very large database may require more memory so as 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 clicks.
