What precisely is Memcached? What is the reason for its expanding recognition among people who take care of databases?
Memcached is a data caching system, which is used to supercharge the speed of database-driven Internet sites by caching the requests and the responses between the website visitor and the server. In other words, every time a certain web page on such a site is visited, the script connects to its database to request the info that should be displayed to the visitor. If the latter clicks on a hyperlink to visit another page, the entire process is repeated and this generates a lot of database requests and higher server load, even more so if the site has a lot of concurrent visitors. Memcached "memorizes" this information exchange, so if any of these pages is accessed again, the script no longer has to fetch any information from the database, since everything is delivered by the Memcached platform. In this way, the overall loading speed of your website will increase and you will enjoy more pleased visitors and they’ll be able to surf through your site faster. In addition, Memcached updates its cache every time any content in the database is altered, so the website visitors will never end up seeing outdated content.
Memcached in Shared Hosting
The Memcached object caching system is offered as an upgrade with every Linux shared package
offered by us and you will be able to start using it once you add it, since the extension that it needs in order to run correctly is already present on our innovative cloud platform. You can request the upgrade from the Hepsia hosting Control Panel, which is available with each and every hosting package and a brand-new section where you can manage Memcached will appear. The upgrade is divided into two parts – the number of instances and the memory, so as to offer you more flexibility. The first one shows the number of the sites that can use the Memcached caching system, whereas the second, which is available in increments of 16 MB, specifies the maximum size of the content that can be cached by the system. A busy site with a very large database may require more memory in order to take an even bigger advantage of Memcached, so if you’d like to upgrade this service, you’ll be able to do it at any given moment with several clicks.
