Memcached is a content caching system, which is used to improve the speed of database-driven Internet sites by caching the requests and the replies between the website visitor and the server. To put it in simple terms, every time a particular web page on such a website is opened, the script sends a query to its database to fetch the information that should be displayed to the visitor. If the latter clicks a link to visit another page, the entire operation is carried out again and this leads to lots of database queries and higher load on the server, even more so if the website has a lot of simultaneous visitors. Memcached "remembers" this exchange of information, so if any of these web pages is accessed again, the script no longer has to request any information from the database, since everything is delivered by the caching platform. In this way, the overall speed of your website will "soar" and you’ll get more pleased visitors and they’ll be able to browse your website faster. Plus, Memcached updates its cache when any data in the database is edited, so the website users will never see out-of-date data.
Memcached in Shared Hosting
Memcached is available as an optional upgrade with each shared hosting package that we offer and if you’d like to use it for any script-driven website that you host on our innovative cloud website hosting platform, you’ll be able to add it in several easy steps via your Hepsia hosting Control Panel. In the meantime, you will get the option to upgrade two different things – the number of instances and the system memory. The first one has to do with the number of the websites that can use Memcached at the same time, so if you need it for several Internet sites, you can order a handful of instances. The second one refers to the total amount of memory that the system will be permitted to use to cache info, so for many websites (or for one single resource-hungry site), you may want to get more memory for better results. The memory is offered in increments of 16 MB and more memory can be added at any moment. With Memcached, each script-driven Internet site hosted on our servers will open incredibly fast.
Memcached in Semi-dedicated Hosting
You can get the Memcached data caching system as an upgrade with all our semi-dedicated hosting and since it works with any script-powered software application, you can use it for every website that you host on our semi-dedicated servers, regardless of what app you have used – WordPress, Mambo or Joomla, a custom-built application, etc. You can request the upgrade through the respective section of the Hepsia hosting Control Panel from which you administer your semi-dedicated server account, and you can choose two separate features – the number of instances and the amount of system memory that they will use. Basically, these things determine the number of the websites that will use the Memcached system and the maximum amount of memory that the system will be able to use in order to store your information. The two features are offered independently for more freedom and one instance does not come bundled with a pre-defined amount of system memory. You can take advantage of Memcached with any sort of site and both you and the site visitors will quickly note the difference in the overall performance.
Memcached in VPS
Memcached comes by default with all Linux VPS packages ordered with our custom-built Hepsia hosting Control Panel. The PHP extension it needs in order to function properly is compiled when the server is configured, so you can start using the content caching platform as soon as your brand new VPS is up and running. The system memory that the Memcached caching platform can use depends on the given VPS plan, but even with the low-end ones, several hundred megabytes will be at your disposal for this platform exclusively. This will allow you to optimize the performance of multiple websites hosted on the VPS server at the same time and to reduce the load on the virtual machine even if you have resource-intensive script-based web portals with multiple viewers. The caching platform can be used with any script – Joomla, Mambo or Drupal, or a custom-built one, and you’ll observe the faster performance shortly after you start using it.
Memcached in Dedicated Hosting
Each dedicated server ordered with our Hepsia Control Panel comes with Memcached already installed by default, so you can start using the content caching system once the dedicated server is set up, without the need to activate or upgrade anything. The amount of memory that Memcached can use depends on the server that you have chosen, but since our servers are quite powerful and due to the fact that it’s likely that you will host resource-demanding websites on them, the minimum amount of memory that the system can use is 3 GB. This will enable you to improve the performance of very large sites with ease and you’ll detect the difference shortly after the Memcached system starts caching database calls. You can make use of the caching system with any database-powered web page, including those that are based on famous Content Management Systems like WordPress and Joomla.
