This script isn't an attempt to be a golden standard. It's just yet another bench script to add to your arsenal. Included are several tests that I think are most beneficial for the end-user. If there's features that you would like to see added, feel free to submit an issue describing your feature request or fork the project!
This script has been tested on CentOS 7, Debian 9, Debian 10, Fedora 30, Ubuntu 16.04, and Ubuntu 18.04. It is designed to not require any external dependencies.
* **dd** - the dd utility is utilized to test disk performance. Both write and read speeds are evaluated by writing to and reading from a test file. __\*Disclaimer__: read speeds may be heavily influenced by cache depending on configuration of the host.
* **iperf3** - the industry standard for testing download and upload speeds to various locations. This script utilizes iperf3 with 8 parallel threads and tests both download and upload speeds. If an iperf server is busy after 10 tries, the speed test for that location/direction is skipped.
* **Geekbench 4** - Geekbench is a benchmarking program that meastures system performance, which is widely used in the tech community. The web URL is displayed to be able to see complete test and individual benchmark results and allow comparison to other geekbench'd systems. The claim URL to add the Geekbench 4 result to your Geekbench profile is written to a file in the directory that this script is executed from.
