The Optimization Method of Multi-modal Data Hierarchical Cache of Portal Website Based on Accessible Characteristics of Data

In view of the high cache miss rate and poor cache optimization effect of traditional methods in application, this paper proposes a multi-modal data hierarchical cache optimization method for portal websites based on data accessibility characteristics. This paper first analyzes the frequency and time characteristics of the multi-modal data of the portal website. Then, it determines the multi-modal data cache value, divides the cache hierarchy according to the relief node space situation, replaces the cached content according to the data cache value, and caches it according to the split hierarchy. Finally, the experiment proves the advantage of the proposed method. The experimental results verify that the cache miss rate of the design method is lower, which can be controlled within 2. 7%, and is better than the comparison method. The method has good cache optimization effect and can be used in the data processing of the portal website.
