Memcached is a content caching system, which is used to enhance the loading speed of database-powered sites by caching the requests and the responses between the website visitor and the server. To put it differently, every time a specific page on such a site is requested, the script calls its database to request the info that should be displayed to the visitor. If the latter clicks a link to visit another page, the whole procedure is repeated and this leads to a lot of database calls and high load on the server, even more so if the website has lots of simultaneous visitors. Memcached "memorizes" this exchange of information, so in case any of these web pages is requested again, the script no longer has to pull any information from the database, since everything is provided by the caching platform. Thus, the overall loading speed of your site will increase and you’ll get more gratified visitors and they will be able to navigate through your site much faster. At the same time, Memcached updates its cache every time any data in the database is altered, so the website visitors will never wind up seeing old content.
Memcached in Website Hosting
If you host script-based sites in a website hosting account with us, you can add Memcached to your shared web hosting package with just a few clicks of the mouse through your Hepsia Control Panel. The upgrade will be available momentarily and, since the needed extension is pre-installed on our advanced cloud website hosting platform, you can start using it straight away. To give you more versatility, we offer two separate 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 comes in increments of 16 MB and you can order as much memory as you want. Logically, the more memory the Memcached caching system is allowed to use, the more data it will cache, so if you have a resource-absorbing site with lots of data, you may need more memory so as to be able to make full use of the power that Memcached can offer you.
