Running a Speed Test on Linux and Windows (10Gbps-Aware)

A quick guide to running reliable speed tests on Linux and Windows, especially for 10Gbps setups.

​
🐧 Speed Test on Linux

We recommend using the Speedtest CLI by Ookla for reliable results.

​
🔧 Installation

Run the following commands to install:

# Add Ookla's repository
curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb.sh | sudo bash

# Install the speedtest tool
sudo apt install speedtest

​
🚀 Running a Basic Speed Test

Once installed, run a simple speed test:

speedtest

⚠️However, the default server might not support 10Gbps speeds, resulting in underwhelming results.

To get accurate high-speed measurements:

​
📋 List Available Servers

speedtest -L

This will output a list of servers with their IDs.

​
🎯 Run Test on a Specific Server

Pick a server that supports high throughput (based on location and provider) and use its ID:

speedtest -s <server-id>

Example:

speedtest -s 12345

​
🪟 Speed Test on Windows

While the command line option is also available, for most users we recommend using the Speedtest app by Ookla.

​
⬇️ Download the App

Download the official Speedtest app from Ookla’s website:

This GUI-based tool provides more stable and optimized results, especially on systems with higher bandwidth.

​
⚠️ Notes on 10Gbps Testing

Just like on Linux, not all servers support 10Gbps. If you’re seeing low results:

  1. Click on the current server name displayed under the speed dial.
  2. From the list that appears, select another server — preferably one known to support higher bandwidth.
  3. Try multiple nearby servers to find the best performance.
