Dynamic quantitative indication method and device for prefetching document

Abstract

The invention provides a dynamic quantitative indication method and a device for prefetching a document. The method comprises the following steps: whether the current candidate predetermined result is the same as the previous candidate predetermined result or not is judged, if so, the accumulation operation or the degressive operation is implemented on the current count value, and if not, the current count value is set to a preset value. The method not only can indicate the state of the current document prefetch behavior, but also can indicate the recent continuous historical representation of the current document prefetch behavior, is simple and visual, has simple operation, and can effectively save the storage space.

Description

technical field [0001] The invention relates to a file system, in particular to a method and device for dynamic modeling and quantitative indication of data access prefetch and other prefetch behavior analysis in the file system. Background technique [0002] With the increasing requirements for data processing and file access speed, instant access to data can no longer meet most data access requirements. More and more file and data prefetching is used in various systems. On the one hand, the size of the data is getting larger and larger, and the local storage of the terminal is almost unrealistic. More and more requests come from the network. The network delay brings about the inefficiency of system processing data. On the other hand, although the access and transmission speeds of local hard disks and networks are increasing rapidly, there is still a widening gap compared with high-speed access requirements such as processors and memory. Therefore, storage architecture,...
