Data caching is a crucial process that affects the loading speed of your website for its visitors. Thanks to caching, the page is not recreated from scratch for each user, allowing for working with large amounts of data in the shortest possible time. As traffic increases, the load on the server grows, and one solution is to use memcached software. Memcached is a software that implements a data caching service in RAM based on a hash table. With the help of a client library (for C/C++, Ruby, Perl, PHP, Python, Java, etc.), it allows caching data in the server's RAM.
