Memcached is a distributed memory object caching system, which is used to supercharge the performance of database-powered sites by caching the queries and the replies between the user and the server. To put it in simple terms, anytime a given web page on such a website is requested, the script sends a query to its database to fetch the info that should be displayed to the website visitor. If the latter clicks on a link to go to another web page, the entire process is performed again and this leads to plenty of database calls and excessive load on the server, even more so if the website has lots of simultaneous visitors. Memcached "remembers" this information exchange, so in case any of these pages is opened again, the script no longer needs to pull any content from the database, since everything is provided by the Memcached platform. In this way, the overall speed of your site will "soar" and you’ll have more gratified visitors and they’ll be able to navigate through your site much faster. Besides, Memcached "refreshes" its cache if any info in the database is updated, so the site users will never see old content.
Memcached in Website Hosting
You can make use of Memcached with all Linux website hosting offered by our company. It is offered as an optional upgrade, which you can add with just a couple of clicks of the mouse through your Hepsia web hosting Control Panel. It needs a PHP extension, which is pre-installed on our cloud website hosting platform, so you can start using Memcached as soon as you order it. The upgrade is divided into two parts, which will give you more freedom depending on the sites that you want to use it for. The first part determines the number of the Internet sites that will use the Memcached caching system, or the so-called ‘instances’, whereas the second one is related to the memory, in other words – to how much content Memcached will be able to cache. You can get more memory in increments of 16 MB and the more memory you’ve ordered, the more content will be cached, which may be a rather good idea for traffic-intensive sites with very large databases and plenty of simultaneous visitors. Thus, you can increase the performance of any script-powered Internet site hosted on our servers with ease.
Memcached in Semi-dedicated Servers
When you acquire any of our semi-dedicated server plans, you will find Memcached as an optional feature in the Upgrades part of the Hepsia Control Panel, so if you wish to use it for any of the Internet sites hosted in the semi-dedicated server hosting account, you can activate it with only a few clicks of the mouse. The object caching platform is suitable for any script-powered application such as WordPress, Joomla, or even a custom-made app, and depending on your demands, you will be able to choose two separate things – how many sites will use the Memcached caching platform, in other words – the number of instances; and how much data will be cached, in other words – the amount of system memory that the platform will use. The two things are not tied to each other, so if you run a traffic-heavy site with a lot of data, you can get one instance and a large amount of system memory. Memcached will improve the performance of your Internet sites soon after you enable it and both you and your website visitors will enjoy much better loading speeds.
Memcached in VPS Servers
You will get Memcached with each of the VPS server plans that we offer if you choose Hepsia as your Control Panel and you will be able to activate the caching platform through the section with the same name. The activation requires a few clicks and you’ll distinguish the difference in the performance of your Internet sites almost instantly. The amount of memory that the Memcached caching platform can employ to store data depends on the given Virtual Private Server plan that you have selected, but in any case it won’t be less than several hundred megabytes, which is quite enough even for several content-rich sites. You can use the Memcached platform with websites driven by Joomla, WordPress or any other app and lower the load on your VPS, which will enable you to continue using the current Virtual Private Server hosting plan instead of upgrading to a more powerful one, as you will simply not need it. The Memcached platform is already being used by famous websites like Wikipedia, Zynga and Reddit, which is an evidence of its efficacy.
Memcached in Dedicated Servers
Each dedicated server ordered with our Hepsia Control Panel comes with Memcached pre-installed by default, so you can start using this distributed memory object caching system as soon as the server is up and running, without the need to upgrade or install anything. The amount of system memory that Memcached can use depends on the very server that you’ve chosen, but as our servers are pretty powerful and given the fact that it’s likely that you will host resource-heavy websites on them, the minimum amount of memory that the caching system can use is 3 gigabytes. This will enable you to accelerate the performance of very popular sites without efforts and you will notice the difference soon after the Memcached system begins caching database requests. You can take full advantage of the Memcached system with any database-powered portal, including those that are based on widely used Content Management Systems like WordPress and Joomla.
