What exactly is Memcached? What is the reason for its expanding level of popularity among users who take care of databases?
Memcached is an object caching system, which is used to increase the overall performance of database-powered Internet sites by caching the requests and the responses between the website visitor and the server. Simply put, every time a specific web page on such a website is accessed, the script queries its database to request the information that should be displayed to the visitor. In case the latter clicks a hyperlink to visit some other page, the whole procedure is carried out again and this generates lots of database queries and high load on the server, especially if the site has lots of simultaneous visitors. Memcached "memorizes" this exchange of information, so if any of these web pages is requested again, the script no longer has to call any information from the database, since everything is provided by the caching platform. In this way, the overall speed of your website will increase and you will get more pleased visitors and they will be able to surf through your website faster. Additionally, Memcached "refreshes" its cache every time any content in the database is modified, so the website users will never wind up seeing old data.
Memcached in Shared Website Hosting
The Memcached memory caching system is offered as an optional upgrade with each Linux shared website hosting package
that we’re offering and you can start using it the moment you activate it, as the extension that it requires so as to run correctly is already available on our innovative cloud platform. You can order the upgrade through the Hepsia hosting Control Panel, which is available with each and every plan and a brand new Control Panel section where you can manage Memcached will appear. The upgrade is subdivided into two parts – the instances and the memory, so as to give you more freedom. The first one refers to the number of the websites which can use the Memcached caching system, while the second, which is available in increments of 16 megabytes, determines the total size of the content that the system can cache. A traffic-intensive website with a very large database may require more memory to take an even bigger advantage of the Memcached caching system, so if you wish to upgrade this feature, you’ll be able to do it at any moment with a couple of clicks.
Memcached in Semi-dedicated Hosting
In case you choose to host your websites in a semi-dedicated server
account, you’ll be able to take advantage of Memcached effortlessly, since the object caching platform’s setup takes a few clicks of the mouse from the Hepsia Control Panel. The extension that it requires is pre-installed on our semi-dedicated servers, so you can start using Memcached as soon as you add it to your semi-dedicated server account. You will be able to choose how many websites can use it and how much data can be cached, in other words – there’re two separate features that can be upgraded – the number of instances and the amount of system memory. You can get more of both, so if one of your Internet sites becomes extremely busy, for example, you can always order more memory. Our system is quite flexible in this regard and we don’t bind a particular number of instances to a pre-defined amount of system memory. You can take advantage of Memcached to boost the loading speed of any script-powered website, including those based on famous Internet apps, such as WordPress or Joomla™
Memcached in VPS
When you get a virtual private server
from us, you will be able to use Memcached at no extra fee, as the memory caching platform is offered with all servers ordered with the Hepsia Control Panel. Even if you’ve got data-heavy websites, you can enhance their performance with ease and the decreased load on your Virtual Private Server will permit you to continue using your current VPS plan instead of migrating to a more powerful one. The amount of system memory that the Memcached platform can use to cache info depends on the package that you’re using, but even with a less powerful one, you’ll get no less than several hundred megabytes, which is considerably more than what you’d get with a shared hosting plan, so the website performance boost will be tremendous. You can take advantage of the Memcached platform with any database-powered application, regardless of whether you have developed it on your own or you are using a ready-to-use one like WordPress, Joomla™

You can enhance the performance of any Internet site, irrespective of what script-based app you rely on or how popular the website is, as the minimum amount of memory that Memcached will be able to use is 3 gigabytes and this amount increases significantly with the more powerful dedicated servers. Shortly after the caching system is activated, it will start caching data anytime someone opens your site, so, once enough info has been stored, you will perceive the decreased load and the enhanced overall performance of your site. The Memcached system is being used by numerous sites, among them popular portals like Zynga, Reddit and Wikipedia, which confirms the effectiveness of the Memcached system.
