Memcached is a widely used memory caching system, which can enhance the loading speed and the overall performance of your Internet sites immensely if they use an API or a database. This is accomplished by caching the requests to the API/database and the responses that are delivered, so if someone searches for a given product on your website, for instance, the database won’t have to be accessed to show the results and the entire procedure will be executed notably faster. This is valid for all sorts of database-driven apps and not only for online shopping portals, as every time a particular page is accessed, the app sends a database query to get the content that should be shown. With Memcached, not only will your site open noticeably faster, but it will also generate much less server load. If any content in the database is modified, the cached replies will also be ‘refreshed’, so the users won’t see any out-of-date information.
