Memcached is a distributed memory object caching system, which is used to enhance the performance of database-powered Internet sites by caching the queries and the replies between the visitor and the server. In other words, anytime a given page on such a website is accessed, the script calls its database to request the information that should be displayed to the visitor. In case the latter clicks on a link to open a different page, the entire process is executed again and this generates lots of database calls and excessive load on the server, even more so if the website has a lot of concurrent visitors. Memcached "remembers" this information exchange, so if any of these web pages is opened again, the script no longer has to extract any information from the database, since everything is provided by the caching platform. Thus, the overall load speed of your website will "soar" and you’ll get more happy visitors and they will be able to navigate through your website faster. Moreover, Memcached "refreshes" its cache if any info in the database is updated, so the site visitors will never end up seeing out-of-date content.
Memcached in Shared Hosting
If you host script-powered websites in a shared hosting account with us, you’ll be able to add the Memcached memory caching system to your plan with only a few mouse clicks via your Hepsia Control Panel. The upgrade will be available immediately and, since the necessary PHP extension is pre-installed on our innovative cloud web hosting platform, you can begin using it right away. To give you more flexibility, we offer two different upgrades related to the number of instances (in other words – how many websites will use Memcached) and to the system memory that the Memcached caching system will use. The latter comes in increments of 16 MB and you can order as much memory as you wish. Logically, the more memory the Memcached caching system is allowed to use, the more content it will cache, so in case you own a traffic-consuming website with a lot of content, you may require more memory in order to be able to take full advantage of the power that Memcached can offer you.
