In another article we learned how to use the sysbench command to benchmark the io speed of a disk drive. Check it here: How to Test (Benchmark) Disk IO Speed with Sysbench in Linux / Ubuntu In this post we shall use a different command line tool called fio (Flexible I/O Tester)....

Sysbench is a command line utility program available on linux that can be used to conduct different types of benchmark tests to measure performance of disk io, memory, cpu and mysql database. In another article we learned how to use sysbench to test ram read/write speed. In this particular...

上述命令会显示硬盘的缓存读取速度 (Cached Read Speed) 和不带缓存的读取速度 (Buffered Disk Read Speed)。3、 fio 命令 fio 是一个灵活的 I/O 性能测试工具,它使用多线程进行测试,可以测试硬盘的读写速度、IOPS 和延迟等不同指标。例如,可以使用以下命令测试硬盘的顺序读取速度:fio --name=read --io...
