With the development of mass data storage and I/O intensive applications , I/O increasingly becomes the perform-ance bottleneck of distributed storage system and the distributed file system is the important way to solve the problem of I /O bottle-neck.How to systematically study the performance factor and optimize scheme of the distributed file system is an important research topic.This paper systematically elaborates the referred performance research of the distributed file system , analyzing the key per-formance impact factors of the distributed file system , and providing the design and performance optimization research of distributed file system.
