Memcached is an object caching system, which is used to supercharge the loading speed of database-powered Internet sites by caching the calls and the replies between the visitor and the server. To put it differently, every time a specific page on such a site is requested, the script connects to its database to fetch the information that should be shown to the visitor. In case the latter clicks on a hyperlink to open some other web page, the whole operation is repeated and this generates lots of database requests and high server load, especially if the site has a lot of concurrent visitors. Memcached "remembers" this exchange of information, so if any of these web pages is accessed again, the script no longer has to fetch any info from the database, since everything is provided by the Memcached platform. Thus, the overall loading speed of your website will "soar" and you’ll have more happy visitors and they’ll be able to navigate through your site faster. At the same time, the Memcached platform "refreshes" its cache when any data in the database is modified, so the visitors will never see out-of-date content.
Memcached in Hosting
The Memcached data caching system comes as an optional upgrade with every Linux hosting package offered by our company and you’ll be able to start using it once you enable it, since the extension that it requires so as to perform properly is already present on our innovative cloud website hosting platform. You can request the upgrade through the Hepsia Control Panel, which comes with each shared hosting package and a brand new Control Panel section where you can manage Memcached will appear. The upgrade is separated into two parts – the number of instances and the system memory, so as to give you more versatility. The first one shows the number of the websites that can use Memcached, whereas the second one, which is available in increments of 16 megabytes, indicates the total size of the content that the system can cache. A heavy-traffic site with a very large database may require more memory to take an even greater advantage of Memcached, so if you’d like to upgrade this service, you’ll be able to do it at any point with several mouse clicks.
