What is the MikroTik Bandwidth Test?

The MikroTik Bandwidth Test is a built-in tool that measures the data transmission rate between two MikroTik devices. It helps administrators evaluate network capacity, identify bottlenecks, and troubleshoot performance issues.

When to Use the Bandwidth Test

The Bandwidth Test is useful in scenarios such as:

• Assessing Network Performance: Determine the maximum throughput of your network.
• Diagnosing Bottlenecks: Identify links or devices causing slow data transfer.
• Capacity Planning: Ensure your network can handle current and future traffic demands.

Requirements for Running a Bandwidth Test

Before running the test, ensure the following:

• Two MikroTik devices: one as the Bandwidth Test Server and another as the client.
• Both devices should have sufficient CPU and memory to handle the test.
• Administrative access to both devices.
• Unrestricted connectivity between the devices (no firewall rules blocking test traffic).

How to Run a Bandwidth Test

Follow these steps to run the Bandwidth Test:

Step 1: Enable Bandwidth Test Server

1. Log in to the MikroTik router that will act as the server.
2. Open the terminal and enable the Bandwidth Test Server:

   /tool bandwidth-server set enabled=yes

Step 2: Run the Bandwidth Test from the Client

1. On the client device, open the terminal or use WinBox.
2. Execute the following command:

   /tool bandwidth-test address=[server IP address] user=[username] password=[password] direction=[direction you want to measure]

   Direction can be `send`, `receive`, or `both` based on the test type.

Step 3: Monitor Results

Monitor throughput, CPU usage, and latency during the test to assess performance.

Interpreting Bandwidth Test Results

The results of the Bandwidth Test include:

• Send Rate: The upload speed from the client to the server.
• Receive Rate: The download speed from the server to the client.
• CPU Load: High CPU usage may indicate that the router is a bottleneck.
• Latency: High latency during the test is suggesting potential network issues.

Best Practices for Bandwidth Testing

• Use a Dedicated Network: Run the test in an isolated environment to avoid interference from other traffic.
• Monitor CPU Usage: Ensure the routers have sufficient CPU resources to handle the test.
• Test Different Directions: Run the test for `send`, `receive`, and `both` directions to get a complete view.
• Analyze Results: Compare the test results with your ISP’s claimed bandwidth or internal expectations.

Conclusion

The MikroTik Bandwidth Test is a powerful tool for assessing network performance and identifying potential bottlenecks. By understanding how to set up and interpret the test, you can maintain a high-performing and reliable network.
