Memcached is a distributed memory caching platform, which is used to improve the speed of database-driven websites by caching the queries and the responses between the website visitor and the server. In simple terms, every time a certain page on such a site is accessed, the script calls its database to request the information that should be shown to the website visitor. In case the latter clicks on a hyperlink to open some other web page, the whole procedure is repeated and this generates lots of database calls and higher load on the server, even more so if the website has a lot of concurrent visitors. Memcached "remembers" this exchange of information, so in case any of these pages is opened again, the script no longer has to cull any content from the database, since everything is provided by the Memcached platform. Thus, the overall load speed of your site will increase and you’ll get more gratified visitors and they’ll be able to browse your site faster. Moreover, the Memcached platform "refreshes" its cache when any data in the database is updated, so the site users will never wind up seeing old data.
Memcached in Semi-dedicated Servers
You can get the Memcached distributed memory object caching system as an optional upgrade with all our Linux semi-dedicated hosting service and since it works with any script-driven software app, you can use it for each website that you host on our semi-dedicated servers, regardless of what app you have used – Mambo, WordPress or Joomla™, a custom-developed app, etc. You can request the upgrade through the respective section of the Hepsia hosting Control Panel from which you manage your semi-dedicated account, and you can choose two different things – the instances and the amount of system memory that they will use. Basically, these things specify the number of the Internet sites that will use the Memcached caching system and the amount of system memory that the system will be able to use in order to cache your content. The two features are offered independently for more freedom and one instance does not come with a particular amount of memory. You can make use of Memcached with any type of website and both you and the visitors will quickly distinguish the difference in the overall performance.
Memcached in Dedicated Servers
Any dedicated server ordered with our Hepsia hosting Control Panel comes with Memcached pre-installed by default, so you can start using this object caching system once your server is ready, without needing to install or upgrade anything. The amount of memory that Memcached can employ depends on the dedicated server that you’ve selected, but as our servers are very powerful and considering the fact that it is likely that you’ll host resource-heavy websites on them, the minimum amount of memory that the caching system can use is 3 gigabytes. This will allow you to optimize the performance of very large sites without any effort and you’ll note the difference soon after Memcached starts caching database queries. You can use the Memcached caching system with any database-powered online portal, including those based on famous CMSs like WordPress and Joomla™.
