What fio commands are being used?

[ZaxLofful]

There isn't a discussion section on this repo, so I just had to ask in a issue.

Wanted to know what command is being used for these tests?

I am trying to re0plciate the same test at the CLI for testing ZFS pools, but cannot get anywhere near the same speeds (even on the same host as with your product) and I am not sure what I am missing...

Can #119 help?
or this?

There are two fio calls in this program. Here to prepare the file and here to run the test.

Basically it calls the following with default GUI settings:

fio
  --output-format=json
  --create_only=1
  --filename=/location/of/test/file/KDM_20230922093345.txt 'Provide filepath on the disk/array volume where you want to run tests. Name of the file makes no difference.'
  --size=1024m
  --zero_buffers=0
  --name=prepare

fio
  --output-format=json
  --ioengine=libaio
  --randrepeat=0
  --refill_buffers
  --end_fsync=1
  --direct=1
  --rwmixread=70
  --filename=/location/of/test/file/KDM_20230922093345.txt 'Must match filename option above.'
  --name=read/write/rw/randread/randwrite/randrw 'Value depends on the specific test.'
  --size=1024m 'Must match size parameter above.'
  --zero_buffers=0
  --bs=1m/4k 'Value depends on the test, but generally block size is 1MB for sequential test and 4KB for random test.'
  --runtime=5
  --rw=read/write/rw/randread/randwrite/randrw 'Matches name parameter.'
  --iodepth=8/1/32/1 'Value depends on the specific test.'
  --numjobs=1

See FIO manual for more information and explanation of each parameter.

Thank you @igorpupkinable, your comment was very helpful.

If anyone also finds it useful, I've shared a small script that runs and summarizes these fio results for several commonly run benchmarks: https://gist.github.com/JohnStarich/fb31b6657d8ad629e87df7a3c611c3bc

Here is FIO JSON report parser in JavaScript with OK-ish output.
