  • 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}}
