A python script that benchmarks the download speeds for the connections defined in one or more wireguard config files

Setup

Install Wireguard, along with any additional dependencies

https://www.wireguard.com/install/

Install Puthon 3.x

https://www.python.org/downloads/

Run the following command to install all python package script dependencies

pip install -r requirements.txt

Generate wireguard config files from your VPN provider

Mullvad example: https://mullvad.net/en/account/#/wireguard-config/?platform=windows

How to run the benchmark script

Open benchmark_wireguard_vpn_servers.py and edit the VPN_CONFIG_DIR variable defined at the top to point to the directory containing all wireguard config files.

Run the script:

Windows note: admin privelages are required in order to make calls to the wireguard client from within the script

python benchmark_wireguard_vpn_servers.py

The script will pipe all stdout output to a file named benchmark_stdout.txt

When the script has finished benchmarking all wireguard configs, it will write the results to a file named benchmark_results.json. This file will be sorted by download speed in descending order and will include information about each config tested (config name, server information, and speedtest information).

Example `benchmark_results.json` output file
