Memcached is a memory caching system, which is used to enhance the speed of database-powered websites by caching the queries and the responses between the user and the server. Simply put, anytime a specific web page on such a site is visited, the script calls its database to fetch the information that should be displayed to the website visitor. In case the latter clicks on a link to open a different page, the whole process is executed again and this leads to numerous database calls and higher server load, especially if the website has a lot of simultaneous visitors. Memcached "memorizes" this information exchange, so in case any of these web pages is accessed again, the script no longer has to call any information from the database, as everything is provided by the caching platform. Thus, the overall load speed of your website will increase and you’ll have more satisfied visitors and they will be able to navigate through your website much faster. Moreover, Memcached "refreshes" its cache if any information in the database is edited, so the visitors will never see old data.
Memcached in Shared Hosting
If you host script-based sites in a shared hosting account with us, you will be able to add the Memcached memory caching system to your plan with only a couple of clicks via your Hepsia hosting Control Panel. The upgrade will be available instantly and, since the PHP extension required for it is already installed on our leading-edge cloud web hosting platform, you can start using it straight away. To give you more flexibility, we offer two different upgrades related to the number of instances (i.e. how many sites will use Memcached) and to the amount of system memory that the Memcached caching system will use. The latter is offered in increments of 16 megabytes and you can order memory as many times as you need. Naturally, the more memory the Memcached caching system is permitted to use, the more content it will cache, so in case you have a traffic-hungry website with lots of data, you may need more memory so as to be able to take advantage of the power that Memcached can offer you.
