Understanding Speed Test Results: Why They May Differ from Your Subscribed Speeds
Introduction
As a valued customer of Teledata ICT, we understand that you rely on accurate speed measurements to ensure you’re getting the service level you’re subscribed to. However, speed test results can sometimes show lower speeds than expected, leading to concerns. This article explains why speed test results can vary, how different tools work, and what you can do if you notice discrepancies.
Common Speed Test Tools
There are several popular speed test tools that customers often use:
- Speedtest.net (by Ookla)
- Fast.com (by Netflix)
- MLab (Measurement Lab)
- iPerf3 (for advanced users and network engineers)
Â
Each tool measures your internet speed differently, and the results can vary based on several factors.

How Speed Tests Work
Speed tests measure the time it takes to download (and sometimes upload) a specific amount of data from a server to your device. The speed is typically measured in megabits per second (Mbps). However, various factors can influence the results:
Â
- Server Location: The location of the test server can impact your speed test results. A server located closer to you will generally show better speeds due to lower latency.
- Network Congestion: The time of day and the number of users on your network can affect speed. Peak hours might result in slower speeds due to higher network usage.
- Device and Connection Type: The device you use and whether you’re connected via Wi-Fi or Ethernet can influence the results. Wi-Fi connections, especially on older routers, might show lower speeds compared to wired connections.
- Routing and Peering Agreements: Different test tools might use servers that are part of different networks, which can be subject to different routing paths and peering agreements. This can lead to variations in speed test results.
- Test Protocol: Tools like Fast.com are optimized for streaming services (e.g., Netflix) and focus on download speeds. On the other hand, iPerf3 allows for more detailed testing, including multiple streams and simultaneous upload/download tests.
Why Your Speed Test Results May Vary
When you subscribe to an internet plan, the speed promised is typically the maximum possible speed under optimal conditions. However, speed tests might not always reflect this maximum due to the reasons mentioned above.
For example:
- Fast.com may show lower speeds because it’s focused on streaming performance rather than overall bandwidth.
- Speedtest.net offers a broader measurement, but results can still vary depending on the chosen server and network conditions.
- iPerf3 can show higher speeds because it measures the maximum capacity of your connection by testing with multiple streams.
What to Do If Your Speed Test Shows Lower Speeds
If you notice that your speed test results are consistently lower than your subscribed speed, consider the following steps:
- Run Multiple Tests: Use different speed test tools (e.g., Speedtest.net, Fast.com, MLab) and at different times of the day to get a comprehensive view of your connection’s performance.
- Check Your Setup: Ensure you’re testing from a device connected via Ethernet, as Wi-Fi can introduce variability. Restart your modem/router and try again.
- Consider External Factors: Remember that factors like network congestion, device performance, and server location can impact results.
- Contact Us: If you’re consistently seeing lower speeds, reach out to our helpdesk. We can run diagnostic tests from our end and investigate further
Conclusion
Speed test results are a useful tool to gauge your internet performance, but they are not always definitive. By understanding how these tools work and what factors can influence the results, you can get a more accurate picture of your internet speed.
