Flexible I/O tester: do an I/O action spawning multiple threads or processes. More information: https://fio.readthedocs.io/en/latest/fio_doc.html.

  • Test random reads:

fio --filename=path/to/file --direct=1 --rw=randread --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=4 --time_based --group_reporting --name=job_name --eta-newline=1 --readonly

  • Test sequential reads:

fio --filename=path/to/file --direct=1 --rw=read --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=4 --time_based --group_reporting --name=job_name --eta-newline=1 --readonly

  • Test random read/write:

fio --filename=path/to/file --direct=1 --rw=randrw --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=4 --time_based --group_reporting --name=job_name --eta-newline=1

  • Test with parameters from a job file:

fio path/to/job_file

  • Convert a specific job file to command-line options:

fio --showcmd path/to/job_file
