This tool estimates your real network throughput when there is packet loss, using the Mathis equation, a widely recognised formula for how TCP performance is affected by packet loss and round-trip time (RTT). Even small amounts of loss can cut throughput dramatically.
Enter your connection details and the calculator shows the bandwidth you can actually expect.
Segment size: 1,500 bytes is the maximum transmission unit (MTU) for Ethernet networks. The average packet size on the internet varies with usage and can be anywhere between 20 and 1,500 bytes. If you are unsure, pick 800 or try a few different sizes.
Understanding why fast internet can still have packet loss helps explain why a high-speed connection may still have problems. You can also learn how to check packet loss on your own connection, or read the packet loss FAQs.
Packet loss and latency together are the biggest drag on remote access performance. Book a free network review and we will help you find out what is slowing your team down.
