Memcached is a memory caching system, which is used to boost the speed of database-powered sites by caching the requests and the replies between the user and the server. In simple terms, every time a specific web page on such a site is requested, the script sends a query to its database to get the info that should be shown to the visitor. In case the latter clicks on a link to go to some other web page, the entire procedure is performed again and this results in lots of database queries and higher server load, especially if the website has a lot of simultaneous visitors. Memcached "remembers" this exchange of information, so if any of these pages is requested again, the script no longer has to pull any data from the database, since everything is delivered by the Memcached platform. In this way, the overall speed of your website will increase and you will enjoy more satisfied visitors and they’ll be able to navigate through your website much faster. Additionally, the Memcached platform "refreshes" its cache whenever any info in the database is changed, so the website visitors will never end up seeing old content.
Memcached in Hosting
When you host script-powered websites in a hosting account with our company, you’ll be able to add Memcached to your hosting package with just a few clicks of the mouse through your Hepsia Control Panel. The upgrade will be available instantly and, since the necessary PHP extension is pre-installed on our avant-garde cloud web hosting platform, you can begin using it straight away. To give you more versatility, we offer two different upgrades related to the number of instances (i.e. how many websites will use Memcached) and to the memory that Memcached will use. The latter is offered in increments of 16 MB and you can add memory as many times as you wish. Naturally, the more memory the Memcached caching system is permitted to use, the more content it will cache, so in case you own a resource-requiring website with lots of content, you may require more memory so as to be able to take full advantage of the power that Memcached can offer you.
