Memcached
What precisely is Memcached? What is the reason for its increasing popularity among users who manage databases?
Memcached is a content caching system, which is used to accelerate the loading speed of database-powered websites by caching the queries and the replies between the website visitor and the server. Simply put, anytime a particular web page on such a website is accessed, the script calls its database to fetch the information that should be displayed to the website visitor. In case the latter clicks a link to go to some other web page, the whole operation is performed again and this leads to multiple database queries and excessive load on the server, especially if the site has lots of concurrent visitors. Memcached "memorizes" this information exchange, so in case any of these pages is visited again, the script no longer has to extract any data from the database, as everything is provided by the Memcached platform. In this way, the overall speed of your site will "soar" and you will have more happy visitors and they will be able to browse your website much faster. Plus, Memcached "refreshes" its cache when any information in the database is altered, so the website users will never end up seeing old content.

Memcached in Website Hosting
The Memcached data caching system comes as an upgrade with each
website hosting that we’re offering and you’ll be able to begin using it as soon as you add it, as the extension that it needs in order to perform properly is already present on our cutting-edge cloud hosting platform. You can request the upgrade via the Hepsia Control Panel, which is offered with each shared hosting plan and a brand-new Control Panel section where you can manage Memcached will show up. The upgrade is separated into two parts – the instances and the memory, so as to give you more freedom. The first one refers to the number of the Internet sites which can use Memcached, whereas the second one, which is available in increments of 16 MB, specifies the total size of the content that can be cached by the system. A heavy-traffic site with a large-size database may need more memory to take an even bigger advantage of Memcached, so if you wish to upgrade this feature, you will be able to do it at any given point with a couple of mouse clicks.

Memcached in Semi-dedicated Servers
If you choose to host your websites in a
semi-dedicated server account, you will be able to take advantage of Memcached effortlessly, since the platform’s setup takes a couple of mouse clicks from the Hepsia Control Panel. The PHP extension that is required is already installed on our semi-dedicated servers, so you can begin using the Memcached caching platform the moment you add it to your account. You will be able to select how many websites can use it and how much content it will cache, i.e. there’re two different features that can be upgraded – the instances and the amount of memory. You can get more of both, so if one of your Internet sites becomes very popular, for example, you can always add more memory to it. Our system is pretty flexible in this regard and we do not tie a particular number of instances to a fixed amount of memory. You can take advantage of Memcached to improve the loading speed of any script-powered website, including those that are based on popular Internet apps, such as WordPress or Joomla
™.

Memcached in Dedicated Servers
Each
dedicated server that’s ordered with our Hepsia hosting Control Panel comes with Memcached already installed by default, so you can begin using this object caching system the moment the dedicated server is completely operational, without needing to upgrade or activate anything. The amount of memory that Memcached can use depends on the dedicated server that you have selected, but since our servers are quite powerful and considering the fact that it’s likely that you’ll host resource-heavy sites on them, the minimum amount of memory that the system can use is three gigabytes. This will enable you to enhance the overall performance of very heavy Internet sites without efforts and you’ll distinguish the difference soon after the Memcached system starts caching database queries. You can take full advantage of the Memcached caching system with any database-driven portal, including those that are based on widely used Content Management Systems such as Joomla
™ and WordPress.
