Redis or Memcached necessary for WordPress?

Are Redis or Memcached necessary for WordPress, or are they excessive additions?

[Rachel S]

For most small WordPress websites, using Redis or Memcached isn’t essential. If your site experiences low traffic and is hosted on a reliable server, then page caching, along with a good PHP version, will handle most performance needs. However, if you begin to implement heavier plugins or dynamic features, object caching can significantly improve load times.

From a server-side perspective, Redis makes sense when WordPress is database-heavy. WooCommerce, membership sites, and LMS platforms benefit the most because they generate a lot of repeated queries. For basic blogs or landing pages, Redis often sits idle and doesn’t justify the added complexity.From a server-side perspective, Redis is beneficial when WordPress relies heavily on its database. Sites using WooCommerce, membership platforms, and learning management systems (LMS) gain the most advantage from Redis, as they tend to generate a high volume of repeated queries. However, for basic blogs or landing pages, Redis often remains underutilized and does not warrant the additional complexity it introduces.
