Memcached is a distributed memory object caching system, which is used to optimize the overall performance of database-powered sites by caching the queries and the responses between the user and the server. To put it in simple terms, every time a specific page on such a website is requested, the script sends a database query to get the info that should be displayed to the website visitor. In case the latter clicks a link to open some other page, the whole operation is executed again and this leads to multiple database requests and excessive server load, especially if the site has a lot of simultaneous visitors. Memcached "memorizes" this information exchange, so in case any of these pages is requested again, the script no longer needs to cull any data from the database, since everything is delivered by the caching platform. In this way, the overall loading speed of your site will "soar" and you’ll have more gratified visitors and they’ll be able to browse your site faster. Plus, the Memcached platform "refreshes" its cache whenever any info in the database is changed, so the website visitors will never wind up seeing out-of-date data.
Memcached in Website Hosting
Memcached is offered as an optional upgrade with each website hosting plan that we are offering and you will be able to start using it once you order it, as the extension that it requires so as to run properly is pre-installed on our leading-edge cloud web hosting platform. You can order the upgrade via the Hepsia Control Panel, which is available with each and every web hosting plan and a new section where you can manage Memcached will show up. The upgrade is divided into two parts – the number of instances and the system memory, so as to give you more freedom. The first one shows the number of the websites which can use the Memcached caching system, whereas the second one, which is offered in increments of 16 megabytes, determines the maximum size of the content that can be cached by the system. A popular site with a large-size database may need more memory to take an even bigger advantage of the Memcached caching system, so in case you need to upgrade this service, you’ll be able to do it at any time with several clicks.
