1. Introduction to Memcached.
Memcached is a system that stores copies of objects and data that are accessed multiple times to increase retrieval speed. It is commonly used to optimize data loading from databases for web-based applications. Initially, the memcached system was developed by Danga Interactive and used for LiveJournal. Memcached then became popular and was used on other websites.
Memcached is a simple, highly scalable, key-based that stores values and objects whenever RAM is available, serving the fastest access, without having to Access the database or resources on the hard disk.
Unlike redis, Directadmin is built into the CustomBuild installation toolkit. When you want to install Memcached on Directadmin we need to go through the SSH command.
