What precisely is Memcached? What is the reason for its increasing popularity among people who take care of databases?
Memcached is a caching system, which is used to increase the load speed of database-driven Internet sites by caching the queries and the replies between the website visitor and the server. To put it simply, anytime a given web page on such a website is requested, the script connects to its database to request the info that should be displayed to the visitor. In case the latter clicks on a hyperlink to open some other web page, the whole process is executed again and this leads to plenty of database queries and excessive server load, particularly if the website has lots of concurrent visitors. Memcached "memorizes" this information exchange, so if any of these pages is opened again, the script no longer has to request any information from the database, as everything is delivered by the Memcached platform. Thus, the overall speed of your site will "soar" and you will get more happy visitors and they’ll be able to navigate through your website faster. Furthermore, Memcached updates its cache whenever any info in the database is changed, so the site users will never wind up seeing outdated content.
Memcached in Shared Website Hosting
The Memcached object caching system is offered as an optional upgrade with each and every shared website hosting offered by our company and you will be able to start using it once you add it, since the PHP extension that it needs in order to work properly is already present on our cutting-edge cloud hosting platform. You can request the upgrade from the Hepsia hosting Control Panel, which is available with each and every shared web hosting package and a new Control Panel section where you can administer Memcached will appear. The upgrade is separated into two parts – the instances and the amount of system memory, so as to give you more versatility. The first one shows the number of the Internet sites that can use the Memcached caching system, while the second one, which is available in increments of 16 MB, specifies the maximum size of the content that can be cached by the system. A regularly visited site with a large-size database may require more memory to take an even bigger advantage of the Memcached caching system, so if you want to upgrade this service, you’ll be able to do it at any given point with several clicks.
