文件系統性能測試工具 Filebench
Filebench 是一款文件系統性能的自動化測試工具,它通過快速模擬真實應用服務器的負載來測試文件系統的性能。它不僅可以仿真文件系統微操作(如 copyfiles, createfiles, randomread, randomwrite ),而且可以仿真復雜的應用程序(如 varmail, fileserver, oltp, dss, webserver, webproxy )。 Filebench 比較適合用來測試文件服務器性能,但同時也是一款負載自動生成工具,也可用于文件系統的性能。
- Multiple workload types support via loadable personalities
- Ships with more than 40 pre-defined personalities, including the one that describe mail, web, file, and database servers behaviour
- Easy to add new personalities using reach Workload Model Language (WML)
- Multi-process and multi-thread workload support
- Configurable directory hierarchies with depth, width, and file sizes set to given statistical distributions
- Support of asynchronous I/O and process synchronization primitives
- Integrated statistics for throughput, latency, and CPU cycle counts per system call
- Tested on Linux, FreeBSD, and Solaris platforms (should work for any POSIX-compliant Operating System) </ul>
