Memcached is an object caching system, which is used to enhance the speed of database-driven Internet sites by caching the calls and the replies between the website visitor and the server. Simply put, anytime a given web page on such a site is visited, the script connects to its database to request the info that should be shown to the visitor. In case the latter clicks on a link to visit some other page, the whole operation is executed again and this results in numerous database requests and higher server load, even more so if the website has lots of concurrent visitors. Memcached "remembers" this exchange of information, so in case any of these pages is opened again, the script no longer needs to call any data from the database, as everything is provided by the caching platform. In this way, the overall speed of your site will increase and you’ll have more gratified visitors and they’ll be able to surf through your site much faster. Additionally, Memcached updates its cache if any information in the database is changed, so the visitors will never end up seeing old data.
Memcached in Shared Hosting
If you host script-driven websites in a shared hosting account with us, you’ll be able to add the Memcached object caching system to your shared hosting package with only a couple of clicks from your Hepsia Control Panel. The upgrade will be available momentarily and, since the PHP extension needed for it is already installed on our leading-edge cloud hosting platform, you can begin using it right away. To give you more flexibility, we offer two different upgrades related to the number of instances (i.e. how many websites will use Memcached) and to the amount of memory that Memcached will use. The latter is available in increments of 16 megabytes and you can add memory as many times as you wish. Logically, the more memory Memcached is permitted to use, the more data it will cache, so in case you’ve got a large-scale site with a lot of data, you may need more memory so as to be able to take advantage of the power that Memcached can give you.
