文件系统性能测试 [英] file system performance testing

问题描述

我正在写一个python脚本，它将在linux文件系统中执行性能测试。所以除了死锁之外，竞争条件和时间还需要执行一个操作（删除，读取，写入和创建）测试应该包含的其他变量/参数？

解决方案文件系统性能测试是一个非常复杂的话题。你可以很容易地犯了很多错误，基本上使你的整个测试毫无价值。

Stony Brook University和IBM Watson Labs已经发表了一篇强烈推荐的期刊论文，存储关于文件系统基准测试，其中他们提出了不同的基准和他们的优点和缺点：对文件系统和存储基准测试进行了为期九年的研究。

他们给出了很多建议，如何设计和实现一个好的文件系统基准测试。正如我所说：这不是一件容易的事。

I am writing a python script that will perform performance test in linux file system. so besides deadlocks, race conditions and time takes to perform an action (delete, read, write and create) what other variables/parameters should the test contain?

解决方案

File system performance testing is a very complex topic. You can easily make a lots of mistakes that basically make your whole tests worthless.

Stony Brook University and IBM Watson Labs have published an highly recommended journal paper in the "Transaction of Storage" about file system benchmarking, in which they present different benchmarks and their strong and weak points: A nine year study of file system and storage benchmarking.

They give lots of advise how to design and implement a good filesystem benchmark. As I said: It is not an easy task.
