How this test works

Internet plans use megabits per second (Mbps), while file transfers are commonly shown in megabytes per second (MB/s). Eight bits equal one byte.

Real-world factors that reduce speed

Protocol overhead

TCP/IP and other headers add extra data.

Network congestion

Traffic and time of day affect throughput.

Server limitations

The source server may throttle speed.

Device limits

Storage or hardware can be a bottleneck.

How to use the result

  1. Use theoretical speed as the technical maximum.
  2. Use practical speed to estimate real file transfers.
  3. Increase overhead for congested Wi-Fi or slower servers.
Why is MB/s lower than Mbps?

Mbps measures bits. File-transfer tools usually show bytes, and every byte contains eight bits.
