# Yet Another Bench Script by Mason Rowe
# Initial Oct 2019; Last update Dec 2020
#
# Disclaimer: This project is a work in progress. Any errors or suggestions should be
# relayed to me via the GitHub project page linked below.
#
# Purpose: The purpose of this script is to quickly gauge the performance of a Linux-
# based server by benchmarking network performance via iperf3, CPU and
# overall system performance via Geekbench 4/5, and random disk
# performance via fio. The script is designed to not require any dependencies
# - either compiled or installed - nor admin privileges to run.
