Software & Tools / Lemoa iperf3
Windows · Network testing
Measure the network—not the internet.
A straightforward graphical interface for testing real throughput between devices and across switches, access points and routed links.
Server and client testing in one application
Select the relevant network interface, start a temporary server or point the client to another iperf3 endpoint. The tool exposes common professional test modes without requiring users to memorise command-line options.
Included capabilities
- Server and client modes
- TCP and UDP throughput testing
- Reverse and bidirectional tests
- Parallel streams and interface selection
- Temporary Windows Private-network firewall rules in server mode
- Readable live output and repeatable test settings
Security note: Server mode requests administrator approval only to manage the temporary firewall access it requires. The rule is removed when the server stops or the application is uninstalled.
