What’s the difference between page caching and object caching?

Page caching creates static HTML versions of your dynamic WordPress pages, storing them for quick access. It’s ideal for mostly static content and significantly reduces server load.

Object caching stores the results of complex database queries in memory (using Redis or Memcached), making it perfect for dynamic content that requires frequent database access.

For page caching, use WP Fastest Cache. For object caching on high-traffic sites, implement Redis Cache along with a Redis server.
