Memcached is a caching system, which is used to supercharge the load speed of database-powered Internet sites by caching the queries and the replies between the user and the server. Put simply, anytime a given web page on such a website is opened, the script sends a database query to get the information that should be shown to the visitor. In case the latter clicks on a link to visit another web page, the entire procedure is executed again and this results in lots of database queries and higher server load, especially if the site has lots of simultaneous visitors. Memcached "memorizes" this exchange of information, so if any of these pages is accessed again, the script no longer has to call any content from the database, as everything is provided by the Memcached platform. In this way, the overall speed of your site will "soar" and you will get more pleased visitors and they will be able to navigate through your site much faster. Also, the Memcached platform updates its cache every time any info in the database is updated, so the visitors will never wind up seeing outdated content.
Memcached in Shared Hosting
If you host script-powered sites in a shared hosting account with us, you can add Memcached to your hosting plan with only a few clicks of the mouse through your Hepsia Control Panel. The upgrade will be available instantly and, since the necessary PHP extension is pre-installed on our leading-edge cloud 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 websites will use Memcached) and to the memory that Memcached will use. The latter comes in increments of 16 megabytes and you can order memory whenever you like. Naturally, the more memory Memcached is allowed to use, the more content it will cache, so if you manage a resource-absorbing website with lots of data, you may require more memory in order to be able to make full use of the power that Memcached can give you.
