What precisely is Memcached? What is the reason for its rising recognition among people who manage databases?
Memcached is an object caching system, which is used to accelerate the loading speed of database-powered sites by caching the requests and the responses between the website visitor and the server. Put simply, every time a particular web page on such a site is accessed, the script sends a database query to request the info that should be shown to the website visitor. If the latter clicks a hyperlink to open a different web page, the whole operation is carried out again and this leads to numerous database requests and high server load, especially if the site has lots of concurrent visitors. Memcached "remembers" this information exchange, so in case any of these web pages is accessed again, the script no longer needs to call any content from the database, as everything is provided by the caching platform. Thus, the overall load speed of your website will "soar" and you’ll get more pleased visitors and they’ll be able to surf through your website much faster. At the same time, the Memcached platform "refreshes" its cache whenever any data in the database is altered, so the users will never see out-of-date data.
Memcached in Website Hosting
You can use the Memcached distributed memory caching system with all website hosting
that we offer. It is available as an upgrade, which you can add with just a couple of mouse clicks from your Hepsia web hosting Control Panel. It requires a PHP extension, which is pre-installed on our cloud web hosting platform, so you can begin using Memcached the moment you order it. The upgrade is subdivided into two parts, which will offer you more freedom depending on the Internet sites that you would like to use it for. The first part concerns the number of the Internet sites that will use Memcached, or the so-called ‘instances’, whereas the second one is related to the system memory, i.e. to how much content the system will be able to cache. You can add more system memory in increments of 16 megabytes and the more memory you’ve ordered, the more data will be cached, which may be a pretty good idea for regularly visited websites with large-sized databases and plenty of simultaneous visitors. In this way, you can increase the loading speed of any script-based website hosted on our cloud servers effortlessly.
Memcached in Semi-dedicated Servers
If you purchase one of our semi-dedicated server
packages, you’ll find Memcached as an optional upgrade in the Upgrades section of the Hepsia hosting Control Panel, so if you would like to use it for any of the websites hosted in the semi-dedicated server hosting account, you can add it with only a few clicks of the mouse. The object caching platform is ideal for any script-driven application like Joomla™
, WordPress, or even a custom-built one, and depending on your needs, you will be able to select two separate things – how many sites will use Memcached, in other words – the number of instances; and how much data will be cached, in other words – the amount of memory that the platform will employ. The two things are not bound to each other, so if you own a popular site with a lot of content, you can get one instance and a large amount of system memory. The Memcached caching platform will improve the overall performance of your sites shortly after you enable it and both you and your website visitors will enjoy better loading speeds.
Memcached in Dedicated Servers
Memcached comes free of charge with all dedicated servers
offered by our company and the sole condition is that the dedicated machine must be ordered with the Hepsia Control Panel. You can use the caching system for any database-powered site, including those that are based on widely used web-based applications – for instance, a WordPress personal weblog or a Joomla™
-powered community portal. Each dedicated server comes with a specific amount of system memory that the Memcached system can use, but the minimum amount you will get is 3 gigabytes, which is sufficient enough to optimize the loading speed of extremely large websites considerably, since this very memory will be dedicated to storing the cached info. The Memcached system will start caching data as soon as it’s enabled, so soon thereafter, you’ll notice the enhanced overall performance of your Internet sites and the lowered load on the dedicated machine. Lots of websites use Memcached to enhance their efficiency, among them famous ones like Wikipedia and Reddit.
