What exactly is Memcached? What is the reason for its increasing level of popularity among users who take care of databases?
Memcached is an object caching platform, which is used to optimize the performance of database-driven sites by caching the calls and the responses between the website visitor and the server. In other words, every time a particular web page on such a site is requested, the script calls its database to fetch the information that should be displayed to the visitor. In case the latter clicks a hyperlink to visit a different page, the whole procedure is executed again and this results in numerous database calls and excessive server load, even more so if the website has a lot of simultaneous visitors. Memcached "memorizes" this information exchange, so if any of these pages is requested again, the script no longer has to fetch any data from the database, as everything is delivered by the caching platform. In this way, the overall load speed of your website will increase and you’ll have more pleased visitors and they will be able to navigate through your website much faster. Plus, Memcached "refreshes" its cache if any info in the database is modified, so the visitors will never see outdated content.
Memcached in Shared Hosting
You can make use of the Memcached distributed memory caching system with all shared hosting service
that we’re offering. It is offered as an upgrade, which you can enable with just a couple of clicks through your Hepsia hosting Control Panel. It needs an extension, which is already installed on our cloud platform, so you can start using Memcached once you order it. The upgrade is separated into two parts, which will offer you more flexibility depending on the websites that you would like to use it for. The first one concerns the number of the sites that will use the Memcached caching system, or the ‘instances’, whereas the second one refers to the memory, i.e. to how much content Memcached will be able to cache. You can order more memory in increments of 16 MB and the more memory you have ordered, the more content will be cached, which may be a very good idea for high-demand websites with large-size databases and many users. In this way, you can optimize the performance of every script-powered site hosted on our servers without efforts.
Memcached in Semi-dedicated Servers
You can get the Memcached distributed memory caching system as an optional upgrade with all our semi-dedicated service
and since it works with any script-driven software app, you can use it for any Internet site that you host on our semi-dedicated servers, irrespective of what application you have used – Joomla™
, WordPress or Mambo, a custom one, etc. You can add the upgrade via the corresponding section of the Hepsia hosting Control Panel from which you administer your semi-dedicated account, and you can choose two separate things – the number of instances and the amount of memory that they will use. In other words, these things define how many Internet sites will use the Memcached system and the total amount of system memory that the system will be able to use in order to cache your content. The two things are offered separately for more flexibility and one instance does not come with a pre-defined amount of system memory. You can take advantage of Memcached with any sort of website and both you and the visitors will quickly perceive the difference in the overall performance.
Memcached in VPS Servers
Memcached is available as standard with all VPS web hosting service
ordered with our in-house developed Hepsia Control Panel. The extension it needs in order to work properly is compiled when the Virtual Private Server is configured, so you can begin using the data caching platform the moment your new server is completely ready. The memory that the Memcached platform can employ depends on the particular plan, but even with the less powerful plans, you’ll get several hundred megabytes that will be at your disposal only for this platform. This will allow you to accelerate the performance of multiple sites hosted on the server at the same time and to reduce the load on the virtual machine even if you have heavy script-powered web pages with numerous visitors. The Memcached platform can be used with any script – Joomla™
, Mambo or Drupal™
, or a custom-built one, and you’ll observe the faster overall performance shortly after you start using it.
Memcached in Dedicated Servers
Memcached is available free of charge with all Linux dedicated servers
offered by us and the one and only requirement is that the dedicated machine must be ordered with the Hepsia hosting Control Panel. You can use the data caching system for any database-powered Internet site, including those that are based on popular web-based apps – for instance, a WordPress personal blog or a Joomla™
-powered community site. Each dedicated machine comes with a certain amount of system memory that the Memcached caching system can employ, but the minimum you’ll get is 3 gigabytes, which is quite enough to improve the loading speed of extremely busy sites substantially, since this very memory will be dedicated to storing the cached information. The system will start caching content once it’s activated, so shortly after that, you will note the improved performance of your sites and the lowered load on your server. Lots of Internet sites use the Memcached system to boost their efficacy, including popular ones like Reddit and Wikipedia.
