Memcached is a distributed memory object caching system, which is used to supercharge the overall performance of database-driven Internet sites by caching the queries and the responses between the visitor and the server. To put it simply, every time a specific page on such a site is accessed, the script calls its database to fetch the info that should be displayed to the visitor. If the latter clicks a hyperlink to go to a different web page, the entire process is repeated and this results in a lot of database queries and excessive server load, even more so if the site has lots of simultaneous visitors. Memcached "remembers" this information exchange, so in case any of these web pages is opened again, the script no longer needs to extract any content from the database, as everything is provided by the caching platform. Thus, the overall load speed of your site will "soar" and you’ll have more gratified visitors and they will be able to navigate through your website faster. Furthermore, Memcached updates its cache if any information in the database is altered, so the website users will never wind up seeing old data.
Memcached in Shared Web Hosting
Memcached comes as an optional upgrade with each and every shared web hosting plan that we’re offering and in case you would like to use it for any script-driven site that you host on our innovative cloud web hosting platform, you’ll be able to order it in a couple of simple steps via your Hepsia hosting Control Panel. In the meantime, you will be given the option to upgrade two separate things – the number of instances and the system memory. The first one refers to the number of the sites that can use the Memcached object caching system at the same time, so if you need it for several sites, you can order a number of instances. The second one refers to the total amount of memory that the system will be able to use in order to cache info, so for a lot of sites (or for one regularly visited site), you should get more memory for better performance. The memory is offered in increments of 16 MB and more memory can be added every time you need it. With the Memcached caching system, every script-based site hosted on our cloud servers will load incredibly fast.
