What exactly is Memcached? What is the reason for its growing popularity among people who maintain databases?
Memcached is an object caching platform, which is used to boost the overall performance of database-driven sites by caching the requests and the replies between the website visitor and the server. Simply put, anytime a particular page on such a site is opened, the script sends a database query to request the information that should be shown to the visitor. If the latter clicks a hyperlink to open a different page, the entire process is carried out again and this results in lots of database queries and excessive server load, especially if the website has a lot of concurrent visitors. Memcached "remembers" this information exchange, so if any of these pages is visited again, the script no longer needs to fetch any data from the database, as everything is provided by the Memcached platform. Thus, the overall speed of your site will "soar" and you will have more happy visitors and they’ll be able to surf through your website much faster. In addition, the Memcached platform "refreshes" its cache every time any data in the database is changed, so the users will never wind up seeing outdated content.
Memcached in Cloud Website Hosting
The Memcached memory caching system comes as an optional upgrade with each and every Linux cloud website hosting package
that we are offering and you’ll be able to begin using it once you enable it, since the PHP extension that it requires so as to run correctly is already available on our innovative cloud web hosting platform. You can order the upgrade via the Hepsia Control Panel, which comes with every shared web hosting plan and a brand-new Control Panel section where you can manage Memcached will appear. The upgrade is divided into two parts – the number of instances and the system memory, so as to offer you more versatility. The first one shows the number of the sites that can use Memcached, while the second one, which is offered in increments of 16 megabytes, indicates the total size of the content that can be cached by the system. A traffic-heavy website with a large database may need more memory to take an even greater advantage of the Memcached caching system, so if you want to upgrade this service, you’ll be able to do it at any given point with several mouse clicks.
Memcached in Semi-dedicated Hosting
You can get the Memcached distributed memory object caching system as an optional upgrade with all our Linux semi-dedicated packages
and since it works with any script-based web application, you can use it for each website that you host on our platform, regardless of what app you have used – Mambo, Joomla™
or WordPress, a custom-built one, etc. You can order the upgrade via the respective section of the Hepsia hosting Control Panel from which you administer your semi-dedicated account, and you can select two separate things – the instances and the amount of system memory that they will use. In other words, these things define the number of the Internet sites that will use the Memcached caching system and how much system memory the system will be able to use to cache your data. The two features are offered separately for more freedom and one instance does not come with a fixed amount of system memory. You can make the most of the Memcached system with any kind of site and both you and the visitors will quickly distinguish the difference in the performance.
Memcached in Dedicated Hosting
Memcached is available for free with all Linux dedicated servers hosting packages
offered by us and the only requirement is that the dedicated server must be ordered with the Hepsia Control Panel. You can use the memory caching system for any database-powered site, including those that are based on widely used apps – for instance, a WordPress online blog or a Joomla™
-driven community site. Each dedicated machine is tied to a certain amount of system memory that the Memcached system can employ, but the minimum you’ll get is three gigabytes, which is sufficient enough to enhance the loading speed of extremely heavy sites immensely, as this memory will be dedicated to storing the cached content. The system will begin caching info as soon as it is activated, so shortly after that, you’ll detect the optimized overall performance of your sites and the decreased load on the server. A lot of Internet sites use the Memcached caching system to improve their efficiency, including famous ones such as Reddit and Wikipedia.
