LAN speed is different from Internet speed

Internet testing includes your ISP and a remote server. LAN testing stops inside your network, helping isolate router, Ethernet and wireless performance.

Bidirectional results matter

The test measures Device A to Device B and Device B to Device A separately because radio conditions, browser scheduling and device CPU can create asymmetry.

Browser LAN test versus iperf

iperf is a dedicated raw TCP or UDP benchmark and remains the right tool for deep engineering work. This test trades some protocol overhead for a simple, installation-free workflow.
