Memcached is a data caching system, which is used to optimize the load speed of database-driven Internet sites by caching the requests and the responses between the user and the server. In simple terms, anytime a certain web page on such a website is opened, the script queries its database to fetch the info that should be displayed to the visitor. In case the latter clicks a link to visit some other page, the whole procedure is performed again and this leads to lots of database requests and higher load on the server, especially if the website has lots of simultaneous visitors. Memcached "memorizes" this information exchange, so if any of these pages is accessed again, the script no longer has to extract any info from the database, since everything is delivered by the Memcached platform. In this way, the overall speed of your website will "soar" and you will enjoy more satisfied visitors and they will be able to navigate through your site much faster. Besides, Memcached "refreshes" its cache whenever any content in the database is altered, so the website users will never wind up seeing old content.
Memcached in Web Hosting
When you host script-powered websites in a web hosting account with us, you’ll be able to add the Memcached distributed memory caching system to your hosting plan with only a couple of clicks through your Hepsia Control Panel. The upgrade will be available instantly and, since the necessary extension is pre-installed on our advanced cloud web hosting platform, you can begin using it straight away. To give you more flexibility, we offer two separate upgrades related to the number of instances (in other words – how many websites will use Memcached) and to the memory that Memcached will use. The latter is offered in increments of 16 MB and you can add memory whenever you like. Naturally, the more memory the Memcached caching system is permitted to use, the more data it will cache, so in case you manage a frequently visited site with lots of content, you may require more memory so as to be able to make the most of the power that Memcached can give you.
Memcached in Semi-dedicated Servers
If you decide to host your websites in a semi-dedicated server account, you can take advantage of Memcached with ease, as the object caching platform’s setup takes a few clicks from the Hepsia hosting Control Panel. The extension that it requires is pre-installed on our servers, so you can start using the Memcached caching platform the moment you add it to your account. You’ll be able to select how many Internet sites can use it and how much data it will cache, i.e. there’re two different features that can be upgraded – the number of instances and the amount of system memory. You can add more of both, so if one of your Internet sites becomes extremely popular, for example, you can always get more memory. Our system is rather flexible in this regard and we don’t bind a particular number of instances to a fixed amount of memory. You can use Memcached to boost the speed of any script-powered site, including those that are based on widely used web apps, such as WordPress or Joomla™.
Memcached in VPS Servers
Memcached comes as standard with all VPS servers that are ordered with our custom Hepsia Control Panel. The extension it requires to work properly is compiled when the VPS server is set up, so you can begin using the content caching platform the moment your new server is completely functional. The memory that Memcached can employ depends on the given VPS plan, but even with the lower-end plans, you’ll get several hundred megabytes that will be at your disposal for this platform exclusively. This will allow you to accelerate the performance of multiple websites hosted on the server simultaneously and to lower the load even if you have traffic-hungry script-driven portals with multiple visitors. Memcached can be used with any script – Drupal™, Mambo or Joomla™, or a custom-built one, and you will see the better overall performance soon after you start using it.
Memcached in Dedicated Servers
Memcached is available for free with all dedicated servers that we’re offering and the only requirement is that the server must be ordered with the Hepsia hosting Control Panel. You can use the distributed memory caching system for any database-powered website, including those based on famous software applications – for example, a WordPress online blog or a Joomla™-driven community website. Each dedicated server is tied to a given amount of system memory that Memcached can employ, but the minimum amount you’ll get is 3 GB, which is quite enough to improve the load speed of extremely heavy websites significantly, since this memory will be dedicated to storing the cached data. The system will start storing data once it is enabled, so shortly after that, you will note the improved performance of your sites and the reduced load on the server. Numerous sites use the Memcached caching system to improve their efficacy, among them famous ones like Wikipedia and Reddit.
