Research on optimization strategy of web cache replacement algorithm

Cache technology has greatly improved the efficiency of data query response in distributed systems, especially in ecommerce and other fields. However, with the expansion of the user scale of the system, it is difficult to meet the requirements of fast query response by relying on a single cache structure. In the highly concurrent request environment, the efficiency of the Web cache replacement algorithm will affect the user's query experience directly. Based on the existing classical cache replacement algorithm, this paper proposes an optimization strategy for the cache weight replacement algorithm. It optimizes the existing cache weight replacement algorithm and partitions the cache space to improve the hit rate of the cache replacement algorithm.
