Fio based filesystem performance utility

fioperf: Fio based filesystem 📂 performance tool

Author: Ritesh Harjani [email protected]

==========================================

Description:

fioperf is a simple fio based filesystem performance testing tool. Main purpose for this is to test different filesystem mount options for increasing number of threads. It also takes care by running each test 3 times and updates the average read + write bandwidth in the sqlite table.

We use this sqlite3 table to then plot the bw graph to test for any scalability problems w.r.t. filesystem mount options/patches.

It is still under development, so stay tuned.

TODO:-

1. Implement small script to provide gnuplot based on sql tables.

Requirements:-

pip3 install json
pip3 install configparser
pip3 install argparse
pip3 install sqlite3

[local.config]:

[global]
BuildConfig=ilock
SqlDatabase=fio_dioread_db.db

[dioread_nolock]					// Note don't use '-' in names. Sqlite3 gives error in creating column with that name
mkfs=mkfs.ext4 -F -b 4096 testfs
mount=mount -t ext4 -o loop,dioread_nolock testfs ./mountdir/
mountdir=./mountdir/

[dioread_lock]
mkfs=mkfs.ext4 -F testfs
mount=mount -t ext4 -o loop testfs ./mountdir/
mountdir=./mountdir/
