Memcached is a distributed memory caching system, which is used to increase the performance of database-powered websites by caching the calls and the replies between the user and the server. Put simply, every time a specific page on such a site is opened, the script connects to its database to fetch the information that should be shown to the website visitor. In case the latter clicks a hyperlink to go to a different web page, the entire operation is performed again and this results in numerous database queries and excessive load on the server, especially if the site has lots of simultaneous visitors. Memcached "memorizes" this exchange of information, so in case any of these web pages is visited again, the script no longer needs to call any data from the database, as everything is delivered by the caching platform. In this way, the overall speed of your website will "soar" and you will enjoy more pleased visitors and they will be able to browse your site faster. Besides, Memcached updates its cache every time any info in the database is altered, so the website users will never see out-of-date data.
Memcached in Shared Hosting
You can use the Memcached data caching system with all shared hosting that we offer. It’s available as an upgrade, which you can get with just a few clicks through your Hepsia website hosting Control Panel. It requires a PHP extension, which is already installed on our cloud web hosting platform, so you can begin using Memcached as soon as you order it. The upgrade is subdivided into two parts, which will offer you more versatility depending on the Internet sites that you’d like to use it for. The first one specifies the number of the sites that will use Memcached, or the so-called ‘instances’, whereas the second one is related to the system memory, in other words – to how much content Memcached will be able to cache. You can get more system memory in increments of 16 megabytes and the more memory you have added, the more content will be cached, which may be a good idea for popular sites with very large databases and numerous simultaneous visitors. In this way, you can improve the speed of any script-powered Internet site hosted on our cloud servers effortlessly.
Memcached in Dedicated Servers
Each dedicated server that’s ordered with our Hepsia Control Panel comes with Memcached pre-installed by default, so you can begin using this distributed memory caching system as soon as the dedicated server is ready, without the need to upgrade or activate anything. The amount of memory that Memcached can use depends on the server that you have picked, but as our servers are extremely powerful and given the fact that it is likely that you will host resource-demanding Internet sites on them, the minimum amount of memory that the caching system can use will be 3 GB. This will allow you to improve the performance of extremely popular sites without effort and you will note the difference soon after the Memcached caching system begins caching database calls. You can use the system with any database-powered online portal, including those that are based on popular CMSs like WordPress and Joomla™.
