Memcached is a data caching system, which is used to optimize the loading speed of database-driven websites by caching the calls and the responses between the visitor and the server. Simply put, anytime a given web page on such a website is requested, the script sends a database query to fetch the info that should be shown to the visitor. In case the latter clicks on a hyperlink to go to some other page, the entire process is repeated and this leads to lots of database calls and high load on the server, especially if the site has lots of simultaneous visitors. Memcached "memorizes" this information exchange, so if any of these pages is opened again, the script no longer has to fetch any data from the database, as everything is delivered by the Memcached platform. Thus, the overall load speed of your site will increase and you’ll enjoy more gratified visitors and they’ll be able to surf through your site faster. Furthermore, the Memcached platform "refreshes" its cache whenever any info in the database is modified, so the site users will never end up seeing outdated data.
Memcached in Shared Web Hosting
When you host script-driven sites in a shared web hosting account with us, you’ll be able to add the Memcached content caching system to your web hosting plan with only a few clicks of the mouse via your Hepsia hosting Control Panel. The upgrade will be available instantly and, since the needed PHP extension is already installed on our innovative cloud web hosting platform, you can start using it right away. To give you more flexibility, we offer two different upgrades related to the number of instances (in other words – how many Internet sites will use Memcached) and to the memory that Memcached will use. The latter is available in increments of 16 MB and you can add memory whenever you like. Logically, the more memory the Memcached caching system is allowed to use, the more content it will cache, so in case you run a resource-hungry site with lots of data, you may need more memory so as to be able to make the most of the power that Memcached can offer you.
