Memcached is a distributed memory caching platform, which is used to supercharge the speed of database-driven websites by caching the requests and the responses between the visitor and the server. Put simply, anytime a specific web page on such a site is visited, the script calls its database to fetch the info that should be shown to the website visitor. If the latter clicks on a hyperlink to visit a different web page, the whole operation is repeated and this results in a lot of database queries and excessive load on the server, especially if the website has a lot of concurrent visitors. Memcached "remembers" this information exchange, so in case any of these pages is opened again, the script no longer has to request any info from the database, as everything is delivered by the caching platform. In this way, the overall loading speed of your website will "soar" and you will get more gratified visitors and they’ll be able to surf through your website much faster. In addition, Memcached "refreshes" its cache every time any information in the database is changed, so the visitors will never see out-of-date data.
Memcached in VPS Servers
If you obtain a VPS server from us, you will be able to use Memcached at no additional cost, as the distributed memory caching platform is offered with all VPSs that are ordered with the Hepsia hosting Control Panel. Even if you run large websites, you’ll be able to increase their overall performance without any effort and the lowered load on the VPS server will enable you to keep your current Virtual Private Server package rather than switching to a more powerful one. The amount of memory that the Memcached platform can use to cache info depends on the package that you’re using, but even with a low-end one, you’ll have at least several hundred MB, which is significantly more than the amount of memory you’d get with a shared web hosting plan, so the website performance boost will be substantial. You can take advantage of the Memcached platform with any database-driven app, regardless of whether you have created it yourself or you are using a ready-to-use one such as OpenCart, WordPress or Joomla™.
Memcached in Dedicated Servers
Each dedicated server ordered with our Hepsia Control Panel comes with Memcached already installed by default, so you can start using this content caching system once the server is completely operational, without the need to install or upgrade anything. The amount of system memory that Memcached can employ depends on the dedicated server that you’ve chosen, but since our servers are really powerful and considering the fact that it is likely that you’ll host resource-hungry websites on them, the minimum amount of memory that the caching system can use will be 3 GB. This will enable you to optimize the performance of very large websites without efforts and you’ll notice the difference soon after the Memcached caching system begins caching database queries. You can take full advantage of the caching system with any database-powered site, including those based on popular CMSs like Joomla™ and WordPress.
