Memcached is a distributed memory object caching system, which is used to accelerate the performance of database-powered sites by caching the queries and the responses between the visitor and the server. To put it differently, every time a particular web page on such a site is requested, the script connects to its database to get the information that should be displayed to the website visitor. In case the latter clicks a link to open another web page, the whole procedure is executed again and this generates lots of database queries and higher server load, especially if the site has a lot of simultaneous visitors. Memcached "memorizes" this information exchange, so in case any of these web pages is opened again, the script no longer needs to call any info from the database, as everything is provided by the Memcached platform. Thus, the overall loading speed of your site will "soar" and you will have more pleased visitors and they’ll be able to browse your site faster. At the same time, the Memcached platform updates its cache every time any information in the database is edited, so the users will never see outdated data.
Memcached in Website Hosting
When you host script-based sites in a website hosting account with our company, you can add the Memcached content caching system to your hosting plan with only a couple of mouse clicks through your Hepsia Control Panel. The upgrade will be available momentarily and, since the required PHP extension is already installed on our advanced cloud web hosting platform, you can begin using it straight away. To give you more flexibility, we offer two separate upgrades related to the number of instances (in other words – how many Internet sites will use Memcached) and to the memory that the Memcached caching system will use. The latter is offered in increments of 16 MB and you can add memory as many times as you wish. Logically, the more memory the Memcached caching system is permitted to use, the more data it will cache, so in case you own a large-sized website with a lot of data, you may need more memory in order to be able to take advantage of the power that Memcached can offer you.
