Memcached is a distributed memory object caching system, which is used to improve the load speed of database-powered sites by caching the queries and the responses between the website visitor and the server. Simply put, anytime a specific page on such a website is opened, the script sends a database query to fetch the info that should be displayed to the visitor. In case the latter clicks on a link to open some other web page, the entire operation is carried out again and this leads to plenty of database calls and high server load, especially if the website has a lot of concurrent visitors. Memcached "memorizes" this information exchange, so if any of these web pages is visited again, the script no longer needs to fetch any data from the database, since everything is delivered by the caching platform. In this way, the overall speed of your website will increase and you will get more pleased visitors and they’ll be able to browse your site much faster. In addition, Memcached updates its cache every time any info in the database is altered, so the site visitors will never end up seeing outdated content.
Memcached in Cloud Web Hosting
The Memcached memory caching system is available as an upgrade with each cloud web hosting plan that we’re offering and you’ll be able to start using it once you order it, since the PHP extension that it needs in order to run properly is already installed on our cutting-edge cloud web hosting platform. You can order the upgrade through the Hepsia Control Panel, which comes bundled with every hosting package and a new section where you can administer Memcached will appear. The upgrade is subdivided into two parts – the number of instances and the amount of system memory, so as to give you more flexibility. The first one refers to the number of the Internet sites which can use the Memcached caching system, while the second, which comes in increments of 16 megabytes, specifies the maximum size of the content that can be cached by the system. A traffic-intensive Internet site with a large-size database may require more memory so as to take an even bigger advantage of Memcached, so in case you want to upgrade this service, you will be able to do it at any given moment with several clicks of the mouse.
Memcached in Semi-dedicated Servers
If you decide to host your websites in a semi-dedicated server account, you will be able to take advantage of Memcached with ease, as the platform’s setup requires several clicks of the mouse from the Hepsia hosting Control Panel. The required extension is already installed on our semi-dedicated servers, so you can begin using the Memcached platform the moment you add it to your account. You will be able to select how many websites can use it and how much information it will cache, i.e. there are two different upgradable features – the number of instances and the amount of system memory. You can get more of both, so if one of your Internet sites becomes very busy, for example, you can always add more memory to it. Our system is stunningly flexible in this regard and we do not bind a particular number of instances to a pre-defined amount of memory. You can use Memcached to increase the speed of any script-powered website, including those that are based on widely used applications, such as Joomla™ or WordPress.
Memcached in Dedicated Servers
Memcached comes for free with all dedicated web hosting plans that we’re offering and the one and only condition is that the server must be ordered with the Hepsia hosting Control Panel. You can use the content caching system for any database-driven site, including those that are based on popular web apps – for example, a WordPress personal diary or a Joomla™-powered community portal. Each dedicated machine comes with a certain amount of system memory that the Memcached system can employ, but the minimum amount you will get is 3 gigabytes, which is quite enough to increase the load speed of very popular sites noticeably, as this very memory will be dedicated to storing the cached data. The system will begin caching data the moment it’s enabled, so shortly thereafter, you’ll detect the enhanced performance of your Internet sites and the decreased load on your server. Numerous sites use the Memcached caching system to increase their efficacy, among them famous ones like Wikipedia and Reddit.
