Memcached is a caching system, which is used to supercharge the load speed of database-powered websites by caching the calls and the replies between the website visitor and the server. In other words, anytime a given web page on such a site is accessed, the script calls its database to request the information that should be displayed to the visitor. If the latter clicks on a link to visit some other web page, the whole operation is carried out again and this results in a lot of database queries and high load on the server, especially if the site has a lot of concurrent visitors. Memcached "memorizes" this exchange of information, so if any of these pages is requested again, the script no longer has to pull any info from the database, since everything is delivered by the caching platform. Thus, the overall speed of your website will "soar" and you will get more gratified visitors and they’ll be able to navigate through your website faster. Moreover, Memcached "refreshes" its cache whenever any info in the database is edited, so the site visitors will never wind up seeing outdated data.
Memcached in Shared Hosting
If you host script-powered websites in a shared hosting account with our company, you will be able to add Memcached to your web hosting plan with just a few clicks via your Hepsia Control Panel. The upgrade will be available instantly and, since the PHP extension needed for it is pre-installed on our advanced cloud platform, you can begin using it right away. To give you more flexibility, we offer two separate upgrades related to the number of instances (i.e. how many Internet sites will use Memcached) and to the amount of memory that Memcached will use. The latter is offered in increments of 16 megabytes and you can order memory whenever you like. Logically, the more memory the Memcached caching system is permitted to use, the more content it will cache, so if you run a regularly visited site with a lot of content, you may require more memory in order to be able to take advantage of the power that Memcached can give you.
