Memcached is an object caching platform, which is used to enhance the load speed of database-powered Internet sites by caching the calls and the replies between the website visitor and the server. In other words, every time a particular page on such a site is opened, the script calls its database to get the information that should be displayed to the website visitor. In case the latter clicks on a hyperlink to visit some other page, the whole process is performed again and this generates multiple database queries and high server load, even more so if the site has a lot of concurrent visitors. Memcached "memorizes" this information exchange, so if any of these web pages is requested again, the script no longer needs to cull any content from the database, since everything is provided by the caching platform. In this way, the overall speed of your website will increase and you will enjoy more satisfied visitors and they’ll be able to navigate through your website faster. Besides, Memcached updates its cache when any data in the database is altered, so the users will never wind up seeing old content.
Memcached in Hosting
If you host script-driven websites in a hosting account with our company, you’ll be able to add Memcached to your shared hosting package with just a few clicks of the mouse from your Hepsia hosting Control Panel. The upgrade will be available instantaneously and, since the PHP extension required for it is pre-installed on our innovative cloud hosting platform, you can start 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 amount of system memory that the Memcached caching system will use. The latter is offered in increments of 16 megabytes and you can order as much memory as you wish. Logically, the more memory the Memcached caching system is allowed to use, the more data it will cache, so if you run a resource-demanding website with a lot of content, you may need more memory in order to be able to make the most of the power that Memcached can give you.
