| 摘 要： | 为实现开源的基于内容存储系统及性能优化,以应对固定内容数据存储的急速增长而带来的对这种存储系统结构的广泛需求,该文设计并实现了清华大学的基于内容存储(THCAS)系统,并对系统性能进行了分析和评价,在此基础上,提出了多线程Hash和存储流水线2种基于内容存储的优化方法。在正常操作系统I/O Buffer和去掉异步I/O 2种情况下,将优化后的系统与原系统的写数据吞吐率和CPU使用率进行测试比较,优化后系统在2种情况下均提升了原系统的写数据性能,多线程Hash提高了150%,而存储流水线提高了25%。

| Abstract: | The rapid increase in the amount of fixed content data is creating more needs for content-aware storage which should be designed based on an open-source implementation.This paper describes a Tsinghua University designed content-aware storage system,THCAS,that uses multi-thread Hashes and a storage pipeline to optimize the system performance.The file-writing throughput and the CPU utilization for an optimized system with and without an I/O buffer are compared with the original system. Tests demonstrate that ... |
