Memcached is a distributed memory caching platform, which is used to accelerate the load speed of database-driven websites by caching the calls and the responses between the visitor and the server. To put it differently, anytime a certain page on such a site is opened, the script queries its database to request the information that should be shown to the visitor. In case the latter clicks on a hyperlink to visit a different page, the whole process is repeated and this generates multiple database queries and excessive load on the server, particularly if the site has lots of simultaneous visitors. Memcached "memorizes" this exchange of information, so in case any of these pages is visited again, the script no longer needs to extract any data from the database, since everything is delivered by the caching platform. Thus, the overall load speed of your site will increase and you’ll have more happy visitors and they’ll be able to navigate through your site much faster. In addition, the Memcached platform "refreshes" its cache whenever any information in the database is edited, so the site visitors will never end up seeing old data.
Memcached in Shared Website Hosting
The Memcached object caching system is offered as an optional upgrade with each and every shared website hosting service that we offer and you can begin using it as soon as you order it, as the PHP extension that it requires so as to function properly is already present on our leading-edge cloud platform. You can request the upgrade via the Hepsia Control Panel, which comes with every plan and a new Control Panel section where you can administer Memcached will appear. The upgrade is separated into two parts – the number of instances and the system memory, so as to give you more freedom. The first one shows the number of the websites that can use Memcached, while the second one, which is available in increments of 16 MB, determines the maximum size of the content that can be cached by the system. A popular website with a large-size database may require more memory so as to take an even greater advantage of Memcached, so if you need to upgrade this feature, you’ll be able to do it at any moment with several clicks.
Memcached in Semi-dedicated Hosting
In case you choose to host your Internet sites in a semi-dedicated server account, you can take advantage of Memcached easily, as the data caching platform’s setup takes a couple of clicks from the Hepsia hosting Control Panel. The PHP extension that is required is already installed on our semi-dedicated servers, so you can begin using Memcached the moment you add it to your account. You’ll be able to choose how many Internet sites can use it and how much data it will cache, i.e. there are two separate upgradable features – the number of instances and the system memory. You can add more of both, so if one of your websites becomes extremely popular, for example, you can always get more memory. Our system is exceptionally flexible in this regard and we do not tie a particular number of instances to a pre-defined amount of system memory. You can use Memcached to improve the speed of any script-powered website, including those that are based on popular applications, such as Joomla or WordPress.
Memcached in VPS Web Hosting
If you get a virtual private server from our company, you will be able to use Memcached at no extra charge, as the platform is available with all servers that are ordered with the Hepsia Control Panel. Even if you’ve got regularly visited websites, you can increase their overall performance with no effort and the reduced load on the VPS will allow you to keep using your current Virtual Private Server plan instead of upgrading to a more powerful one. The amount of memory that Memcached can use to cache information depends on the package that you’re using, but even with a low-end one, you will have at least several hundred MB, which is considerably more than what you’d get with a shared hosting package, so the website performance boost will be great. You can use the Memcached platform with any database-driven application, irrespective of whether you’ve developed it on your own or you’re using a ready-made one like Joomla, WordPress or OpenCart.
Memcached in Dedicated Servers Hosting
Memcached is available for free with all Linux dedicated hosting services offered by us and the only condition is that the dedicated server must be ordered with the Hepsia Control Panel. You can use the distributed memory caching system for any database-powered site, including those based on popular web apps – for instance, a WordPress weblog or a Joomla-powered social networking website. Each dedicated server comes with a given amount of system memory that the Memcached system can employ, but the minimum amount you’ll get is 3 gigabytes, which is quite enough to optimize the speed of extremely popular sites greatly, since this very memory will be dedicated to storing the cached info. The system will begin caching info as soon as it is enabled, so soon after that, you’ll distinguish the optimized overall performance of your Internet sites and the reduced load on your dedicated server. A lot of websites use Memcached to enhance their efficiency, including famous ones such as Reddit and Wikipedia.
