A Content Delivery Network (CDN) caches and distributes static and dynamic web content across multiple geographically distributed edge servers, reducing latency for global users. This directly addresses page-loading delays caused by distance from the primary data centers. RASP is for runtime application security, not latency. Remote journaling is for data replication, not performance optimization. SASE can improve security and WAN routing, but a CDN is purpose-built for content delivery performance.
