Caching is the most appropriate solution to improve response time for static content, such as sponsor-related data on the entry pages. Caching stores frequently accessed data closer to users, reducing the need to retrieve it from the database repeatedly. This results in faster load times, especially during high-traffic events. While scalability (horizontal or vertical) might address overall system performance, caching specifically targets improving the speed of accessing static content. CASP+ emphasizes caching as a performance optimization technique for handling high-demand, static web content.
