Redis vs Memcached vs file_get_contents

This technical article benchmarks Redis, Memcached, and PHP's file_get_contents for caching in a single-server environment. It details a PHP-based test showing that reading from the local filesystem (leveraging the Linux kernel page cache) can be significantly faster than using in-memory stores like Redis or Memcached when connection overhead is considered, challenging common assumptions about caching tools.
