Prefetch
Prefetch is a performance optimization technique in computing that involves loading data or resources into a cache before they are actually needed by a program or system. It is commonly used in web development, operating systems, and hardware to reduce latency by anticipating future requests based on patterns or heuristics. This proactive approach helps improve user experience by making applications feel faster and more responsive.
Developers should learn and use prefetching when building high-performance applications, especially in web development for faster page loads, in database systems to optimize query performance, and in gaming or real-time systems to minimize lag. It is crucial for scenarios where latency is critical, such as e-commerce sites, streaming services, or data-intensive applications, as it can significantly reduce wait times and enhance overall efficiency.
