Memcached is a distributed memory caching system, which is used to improve the loading speed of database-driven Internet sites by caching the calls and the responses between the visitor and the server. In other words, anytime a certain page on such a site is visited, the script connects to its database to fetch the info that should be displayed to the website visitor. If the latter clicks on a link to open a different page, the entire procedure is repeated and this leads to plenty of database calls and high load on the server, even more so if the website has a lot of simultaneous visitors. Memcached "remembers" this information exchange, so in case any of these web pages is opened again, the script no longer needs to call any content from the database, as everything is provided by the Memcached platform. Thus, the overall loading speed of your site will "soar" and you will enjoy more gratified visitors and they will be able to browse your website faster. In addition, the Memcached platform updates its cache when any info in the database is changed, so the users will never wind up seeing outdated data.

Memcached in Shared Hosting

The Memcached caching system comes as an optional upgrade with each and every Linux shared hosting that we’re offering and you’ll be able to start using it as soon as you enable it, as the PHP extension that it requires so as to work correctly is already available on our leading-edge cloud web hosting platform. You can request the upgrade through the Hepsia Control Panel, which comes with each and every hosting package and a new Control Panel section where you can manage Memcached will appear. The upgrade is subdivided into two parts – the number of instances and the system memory, so as to offer you more freedom. The first one refers to the number of the sites that can use the Memcached caching system, whereas the second one, which is offered in increments of 16 MB, specifies the total size of the content that the system can cache. A busy site with a large-size database may require more memory to take an even bigger advantage of Memcached, so if you want to upgrade this feature, you will be able to do it at any given time with a few mouse clicks.

Memcached in Semi-dedicated Hosting

If you decide to host your Internet sites in a semi-dedicated server account, you will be able to take advantage of Memcached easily, since the caching platform’s activation requires a couple of clicks of the mouse from the Hepsia hosting Control Panel. The extension that is required is already installed on our servers, so you can begin using the Memcached caching platform as soon as you add it to your semi-dedicated server account. You’ll be able to choose how many websites can use it and how much information can be cached, i.e. there’re two separate features that can be upgraded – the instances and the memory. You can add more of both, so if one of your websites becomes very popular, for instance, you can always get more memory. Our system is quite flexible in this regard and we don’t tie a specific number of instances to a fixed amount of system memory. You can use the Memcached platform to increase the speed of any script-driven website, including those based on famous Internet applications, such as WordPress or Joomla.

Memcached in VPS Web Hosting

Memcached is available as standard with all Linux VPS web hosting ordered with our custom-built Hepsia Control Panel. The PHP extension it requires in order to work properly is compiled when the VPS is set up, so you can start using the content caching platform the moment your brand new virtual server is ready. The system memory that the Memcached platform can use depends on the particular plan, but even with the low-end plans, several hundred megabytes will be at your disposal for this platform exclusively. This will allow you to boost the performance of multiple websites hosted on the server simultaneously and to lower the load on the virtual machine even if you own resource-consuming script-powered websites with a lot of visitors. The platform can be used with any script – Joomla, Mambo or Drupal, or a custom-developed one, and you will detect the better overall performance soon after you start using it.

Memcached in Dedicated Servers Hosting

Memcached comes free of charge with all Linux dedicated servers hosting offered by us and the sole requirement is that the dedicated machine must be ordered with the Hepsia Control Panel. You can use the distributed memory caching system for any database-powered site, including those that are based on widely used software applications – for instance, a WordPress personal journal or a Joomla-powered community web portal. Each server comes with a specific amount of memory that Memcached can employ, but the minimum amount you’ll get is 3 GB, which is quite enough to optimize the loading speed of very large sites enormously, as this very memory will be dedicated to storing the cached content. The system will start storing content the moment it’s activated, so shortly thereafter, you’ll detect the optimized overall performance of your Internet sites and the lowered load. A lot of Internet sites use the Memcached system to boost their efficacy, among them popular ones such as Wikipedia and Reddit.
