- Test random reads:
|
|
|
|
`sudo 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:
|
|
|
|
`sudo 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:
|
|
|
|
`sudo fio --filename={{path/to/file}} --size=500GB --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:
|
|
|
|
`sudo fio {{path/to/job_file}}`
|
|
|
|
- Convert a specific job file to command-line options:
|
|
|
|
`fio --showcmd {{path/to/job_file}}`
