⚠️ windows_first

⚠️ missing_linux_example

⚠️ windows_tools

Summary:

The documentation demonstrates a strong Windows bias throughout. All example commands, including installation and usage of the Azure Connectivity Toolkit (AzureCT), are provided exclusively in PowerShell, with no Linux shell or cross-platform alternatives. The toolkit itself is a PowerShell module, and instructions for installing supporting tools (iPerf, PSPing) and configuring firewall rules are Windows-centric. The test environment and reference results are based on Windows Server, and there is no guidance for running equivalent tests or setup on Linux hosts. Linux is only mentioned in passing (e.g., 'the other can be either Windows or Linux'), but no practical Linux instructions or examples are provided.

Recommendations:

Provide equivalent Linux shell (bash) examples for all PowerShell commands, including installing and running iPerf and collecting results.
Document how to perform link performance tests using native Linux tools (e.g., iPerf, netcat, traceroute) without requiring AzureCT or PowerShell.
Include instructions for configuring Linux firewalls (e.g., ufw, firewalld, iptables) to allow necessary test traffic.
Offer sample test scenarios where both endpoints are Linux, or where the local or remote host is Linux.
Clarify any limitations or differences in test methodology or results when using Linux versus Windows.
If AzureCT is not available for Linux, recommend open-source or cross-platform alternatives and provide usage guidance.
