Embodiment Construction

[0018] The present invention is a method for evaluating the performance of a Linux file system. The method evaluates the performance of a Linux file system from three dimensions, specifically including: microscopic reading and writing bandwidth testing, and evaluating Linux by simulating multiple IO operation application scenarios. Test the microscopic read and write bandwidth of the file system; test the throughput of transaction operations, test the file operation throughput of the Linux file system through the transaction cross cycle operation based on random probability; test the macro typical application simulation test, through the scalable The load model construction method simulates typical application scenarios to evaluate the real working performance of the Linux file system.

[0019] 1. Micro reading and writing bandwidth test

[0020] The design of micro reading and writing test scenarios is mainly divided into six steps. The specific description is as follows:

Abstract

The invention provides a performance test method for a Linux file system. The method evaluates performance of the Linux file system through three dimensions and particularly comprises a micro reading-writing bandwidth test: performing a test on micro reading-writing bandwidth of the Linux file system by simulating multiple application scenes of input-output (IO) operation; an affair operation throughput test: performing a test on affair operation throughput of the Linux file system through an affairs cross circulation operation mode based on random probability; and a macro typical application simulation test: simulating a typical application scene through a construction mode based on a multithreading expandable load model to evaluate real working performance of the Linux file system. By means of the method, test coverage is effectively enlarged under the premise of ensuring correctness.

Description

technical field [0001] The invention relates to the technical field of open source operating systems, in particular to a performance testing method for Linux file systems. Background technique [0002] At present, the performance testing method for the Linux file system is mainly a benchmarking method. The so-called benchmark test is to realize the quantitative and comparable test of a certain performance index of a class of test objects by designing scientific test methods, test tools and test systems. Benchmark testing tools are broadly divided into three categories: Micro-benchmarks (that is, micro-benchmark testing tools), Macro-benchmarks (macro-benchmark testing tools), and Replaying traces (replayable trace files). [0003] The Micro-benchmarks test of the Linux file system is mainly aimed at testing one or more specific operating performances of the file system. The test load is usually composed of different types of operations to highlight a certain aspect or aspec...
