Caching
The VIP Platform’s infrastructure includes several caching layers to enhance site performance.
-
Page cache
The page cache is the first level of caching that is encountered by each request made to a WordPress or Node.js environment on the VIP Platform. Responses from origin are cached at VIP’s global network of edge cache server locations for future requests.
-
Object cache
The WordPress object cache is the second layer of caching that is encountered by requests that pass through the page cache and are routed to the origin servers. The object cache stores common or expensive operations directly into memory so that subsequent requests can quickly access them.
-
Query cache
The Query Cache provides light-weight and transparent in-memory caching of many database queries (such as post lookups) which reduces the overall load on the database and results in a faster, more-scalable site.
-
Static asset caching
Static assets for WordPress and Node.js environments are cached and served by VIP’s edge cache servers.
-
Disable WordPress Core’s term cache priming
Versions of WordPress Core prior to 6.3 prime the term and/or meta caches after certain queries. This can result in performance issues and much longer than normal transaction times.
-
Uncached functions
Some functions in WordPress Core are purposely uncached, and will always result in an SQL query when called. This can have performance implications for a site.
