Pre-warming the Cache
Pre-warming the cache is the proactive process of populating a cache with content before any user requests it. After a cache is purged (for example, following a deployment), Speed Kit's system uses RUM data to identify the most popular and important pages. It then automatically fetches this content to "pre-warm" the Edge Cache nodes around the world. This strategy significantly increases the cache-hit ratio, ensuring that users immediately receive a fast, cached response without having to first experience a slow "cache miss."
