This paper focuses on the key technology adopted in the data path of LionFS,which is an object-based cluster file system,including the direct data transmission mechanism and prefetch policy based on the access information of workload.Performance test results show that read performance increases by 70% with the data path pipelined by prefetch.Read/write performance increases by 24%/28% due to elimination of memory copy by direct data transmission.
