Memcached is a distributed memory caching platform, which is used to enhance the loading speed of database-driven sites by caching the queries and the replies between the website visitor and the server. In other words, every time a given page on such a website is visited, the script sends a database query to fetch the information that should be shown to the visitor. In case the latter clicks a hyperlink to open a different page, the entire operation is executed again and this leads to multiple database requests and excessive server load, particularly if the website has a lot of simultaneous visitors. Memcached "remembers" this information exchange, so if any of these pages is accessed again, the script no longer has to pull any content from the database, since everything is delivered by the Memcached platform. Thus, the overall loading speed of your website will increase and you’ll get more gratified visitors and they will be able to navigate through your site faster. Besides, the Memcached platform updates its cache when any content in the database is edited, so the visitors will never see old data.
Memcached in Cloud Website Hosting
The Memcached content caching system is offered as an upgrade with every Linux cloud website hosting that we’re offering and you can begin using it the moment you add it, as the PHP extension that it needs so as to perform properly is already available on our leading-edge cloud platform. You can order the upgrade from the Hepsia Control Panel, which comes bundled with each shared hosting package and a new section where you can administer Memcached will appear. The upgrade is subdivided into two parts – the instances and the system memory, so as to offer you more versatility. The first one refers to the number of the websites which can use the Memcached caching system, whereas the second one, which is available in increments of 16 megabytes, specifies the total size of the content that the system can cache. A heavy-traffic website with a very large database may need more memory so as to take an even greater advantage of the Memcached caching system, so in case you need to upgrade this feature, you will be able to do it at any moment with a couple of clicks.
Memcached in Dedicated Servers Hosting
Each dedicated server that’s ordered with our Hepsia hosting Control Panel comes with Memcached already installed by default, so you can start using the distributed memory caching system as soon as the server is ready, without having to activate or upgrade anything. The amount of memory that Memcached can employ depends on the very server that you’ve selected, but as our servers are quite powerful and given the fact that it is likely that you will host resource-requiring Internet sites on them, the minimum amount of memory that the system can use is three gigabytes. This will allow you to optimize the overall performance of extremely busy sites without effort and you will observe the difference shortly after the Memcached system begins caching database queries. You can use the system with any database-driven web page, including those based on famous Content Management Systems such as WordPress and Joomla™.
