Memcached is a data caching system, which is used to optimize the loading speed of database-powered Internet sites by caching the queries and the replies between the user and the server. Simply put, anytime a particular page on such a site is visited, the script sends a database query to get the information that should be displayed to the visitor. In case the latter clicks on a link to open some other web page, the whole process is executed again and this results in multiple database queries and higher server load, particularly if the site has lots of concurrent visitors. Memcached "remembers" this information exchange, so if any of these web pages is opened again, the script no longer has to call any info from the database, as everything is provided by the Memcached platform. In this way, the overall load speed of your website will "soar" and you will enjoy more gratified visitors and they will be able to surf through your site much faster. Additionally, the Memcached platform "refreshes" its cache whenever any information in the database is updated, so the site visitors will never end up seeing old data.
Memcached in Website Hosting
Memcached comes as an optional upgrade with each and every website hosting package offered by our company and in case you would like to use it for any script-powered site that you host on our leading-edge cloud website hosting platform, you’ll be able to enable it in a couple of easy steps through your Hepsia Control Panel. During the process, you’ll be offered the option to upgrade two different features – the number of instances and the memory. The first one refers to the number of the Internet sites that can use the Memcached distributed memory caching system simultaneously, so if you need it for several Internet sites, you can order a handful of instances. The second one has to do with the total amount of memory that Memcached will be able to use in order to cache data, so for lots of sites (or for one frequently visited site), you may want to get more memory for better performance. The memory comes in increments of 16 megabytes and more memory can be ordered at any time. With Memcached, every script-powered website hosted on our cloud servers will open amazingly fast.
