Memcached is a distributed memory object caching system, which is used to optimize the speed of database-powered sites by caching the requests and the responses between the visitor and the server. Simply put, every time a certain web page on such a website is visited, the script connects to its database to get the info that should be displayed to the website visitor. In case the latter clicks a link to visit some other page, the entire process is repeated and this generates plenty of database queries and excessive load on the server, especially if the website has a lot of simultaneous visitors. Memcached "remembers" this information exchange, so if any of these web pages is opened again, the script no longer needs to request any information from the database, since everything is delivered by the Memcached platform. Thus, the overall speed of your site will "soar" and you’ll enjoy more pleased visitors and they’ll be able to surf through your site faster. Additionally, the Memcached platform "refreshes" its cache every time any content in the database is edited, so the users will never end up seeing out-of-date content.

Memcached in Website Hosting

The Memcached caching system is offered as an upgrade with each website hosting that we’re offering and you’ll be able to start using it the moment you order it, as the extension that it requires in order to work properly is already present on our avant-garde cloud web hosting platform. You can request the upgrade through the Hepsia Control Panel, which is included with each shared web hosting package and a new section where you can administer Memcached will show up. The upgrade is subdivided into two parts – the instances and the system memory, so as to offer you more freedom. The first one shows the number of the Internet sites which can use Memcached, while the second, which is offered in increments of 16 megabytes, indicates the maximum size of the content that the system can cache. A traffic-intensive Internet site with a very large database may need more memory to take an even greater advantage of the Memcached caching system, so if you need to upgrade this feature, you will be able to do it at any time with a few clicks.

Memcached in Semi-dedicated Servers

If you decide to host your sites in a semi-dedicated server account, you can take advantage of Memcached easily, since the distributed memory caching platform’s activation takes a few clicks from the Hepsia hosting Control Panel. The required extension is already installed on our servers, so you can begin using the Memcached platform the moment you add it to your semi-dedicated server account. You’ll be able to select how many Internet sites can use it and how much data can be cached, i.e. there’re two separate 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 sites becomes very busy, for example, you can always order more memory. Our system is rather flexible in this regard and we do not bind a specific number of instances to a pre-defined amount of memory. You can use Memcached to accelerate any script-powered Internet site, including those based on widely used Internet applications, such as WordPress or Joomla.

Memcached in VPS Servers

Memcached is included by default with every VPS server that we’re offering as long as you choose Hepsia as your Control Panel, so you won’t have to pay any extra cash to be able to take advantage of the maximum capacity of this data caching system. The more powerful VPS package you pick, the more memory Memcached will have for information storage purposes, but you’ll have no less than several hundred MB at all times, which is much more than the amount of memory you would get with a shared hosting package. This will allow you to use Memcached for lots of Internet sites, irrespective of how large they are, which in turn goes to say that you can use a lower-end plan for them without overloading your virtual server. The caching system is excellent for script-based apps such as WordPress, Joomla, OpenCart or Mambo, and you can use it even with a custom-built app. Soon after you enable Memcached, it will begin storing information and you will detect the improved performance of your sites.

Memcached in Dedicated Servers

Memcached comes for free with all dedicated service that we’re offering and the only requirement is that the server must be ordered with the Hepsia Control Panel. You can use the distributed memory caching system for any database-powered Internet site, including those that are based on famous Internet applications – for instance, a WordPress online diary or a Joomla-powered social networking website. Each dedicated machine is tied to a given amount of system memory that the Memcached system can use, but the minimum you’ll get is three gigabytes, which is sufficient enough to accelerate very popular sites tremendously, as this memory will be dedicated to storing the cached information. The Memcached system will start storing information once it is activated, so shortly after that, you’ll note the improved performance of your websites and the lowered load on your dedicated server. Plenty of Internet sites use the Memcached system to improve their effectiveness, among them popular ones such as Wikipedia and Reddit.
