Replacements
Listings that take over the same core job as NTttcp.
iPerf3
Measures how fast a network link really is between two machines you control, which a speed test cannot.
iPerf3 is the standard cross-tool benchmark with TCP, UDP and SCTP and JSON output, officially supported on Linux, FreeBSD and macOS with third-party Windows builds.
nuttcp
Command-line tool for measuring TCP and UDP network throughput.
nuttcp measures TCP and UDP throughput on Windows, macOS and Linux, suited to scripting, and also needs the tool running at both ends.
Flent
Network benchmarking tool that runs repeatable tests with netperf and iperf and plots the results.
Flent runs repeatable tests built on netperf and iperf with plotting and a GUI, but is Linux-oriented and needs a test server.
