Memcached is a distributed memory caching platform, which is used to supercharge the performance of database-driven websites by caching the calls and the replies between the visitor and the server. Simply put, anytime a specific page on such a website is accessed, the script calls its database to request the information that should be displayed to the website visitor. In case the latter clicks on a link to go to a different web page, the whole procedure is carried out again and this leads to plenty of database queries and excessive load on the server, even more so if the site has lots of concurrent visitors. Memcached "memorizes" this information exchange, so in case any of these web pages is opened again, the script no longer needs to extract any information from the database, as everything is provided by the Memcached platform. In this way, the overall speed of your site will increase and you will have more happy visitors and they will be able to surf through your website faster. Additionally, Memcached updates its cache every time any info in the database is edited, so the website users will never end up seeing old content.
Memcached in Cloud Website Hosting
The Memcached object caching system is available as an optional upgrade with every cloud website hosting plan that we offer and you can begin using it as soon as you activate it, as the PHP extension that it requires in order to work correctly is already available on our leading-edge cloud platform. You can request the upgrade through the Hepsia Control Panel, which is available with every web hosting plan and a new Control Panel section where you can manage Memcached will appear. The upgrade is separated into two parts – the number of instances and the memory, so as to offer you more versatility. The first one shows the number of the sites which can use Memcached, whereas the second one, which comes in increments of 16 megabytes, indicates the maximum size of the content that can be cached by the system. A frequently visited website with a large-sized database may need more memory so as to take an even bigger advantage of the Memcached caching system, so in case you’d like to upgrade this feature, you’ll be able to do it at any point with a couple of mouse clicks.
Memcached in Semi-dedicated Servers
You can add the Memcached memory caching platform to any of the semi-dedicated plans that we offer and use its full capacity for any script-driven Internet site hosted on our servers. The upgrade is accessible through the Hepsia hosting Control Panel and you can select two features – the instances and the amount of memory. These things show how many sites can use the Memcached caching platform and how much memory it will use to cache your information. You can select them separately, since one instance is not linked to a specific amount of memory, so you can use a lot of memory for a single resource-consuming website, for example. This feature comes in increments of 16 megabytes and you can order as much memory as you wish. The platform can be used with any script-driven site irrespective of its type, including those based on widespread software apps like Joomla, WordPress or Drupal, and lots of companies like Wikipedia and Zynga are already using it to accelerate the performance of their websites.
Memcached in Dedicated Servers
Any dedicated server that’s ordered with our Hepsia Control Panel comes with Memcached already installed by default, so you can start using the memory caching system once your server is fully ready, without having to upgrade or install anything. The amount of system memory that Memcached can use depends on the server that you’ve selected, but since our servers are extremely powerful and considering the fact that it’s likely that you will host resource-consuming sites on them, the minimum amount of memory that the system can use is 3 gigabytes. This will allow you to enhance the performance of extremely busy sites with ease and you will observe the difference shortly after the Memcached system begins caching database requests. You can take full advantage of the Memcached caching system with any database-driven web portal, including those based on popular Content Management Systems like Joomla and WordPress.
