Memcached is a distributed memory object caching platform, which is used to optimize the speed of database-powered Internet sites by caching the requests and the responses between the website visitor and the server. In other words, every time a particular web page on such a site is accessed, the script sends a query to its database to request the info that should be shown to the visitor. In case the latter clicks on a link to go to some other page, the whole operation is repeated and this results in lots of database requests and higher server load, even more so if the website has lots of concurrent visitors. Memcached "memorizes" this information exchange, so in case any of these pages is visited again, the script no longer has to cull any information from the database, as everything is provided by the caching platform. Thus, the overall loading speed of your site will increase and you’ll have more gratified visitors and they will be able to browse your site faster. Besides, Memcached "refreshes" its cache when any info in the database is changed, so the site visitors will never see outdated content.

Memcached in Web Hosting

The Memcached object caching system is offered as an optional upgrade with each and every Linux web hosting that we offer and you will be able to start using it the moment you activate it, since the PHP extension that it requires so as to function properly is pre-installed on our avant-garde cloud website hosting platform. You can order the upgrade from the Hepsia Control Panel, which comes bundled with every shared hosting plan and a brand-new Control Panel section where you can manage Memcached will show up. The upgrade is separated into two parts – the 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, which comes in increments of 16 megabytes, determines the total size of the content that can be cached by the system. A frequently visited site with a very large database may require more memory in order to take an even bigger advantage of Memcached, so in case you need to upgrade this feature, you’ll be able to do it at any time with several mouse clicks.
