Description

Iperf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the bandwidth, loss, and other parameters.

This version, sometimes referred to as iperf3, is a redesign of an original version developed at NLANR/DAST. iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. Iperf3 also has a number of features found in other tools such as nuttcp and netperf, but were missing from the original iperf. These include, for example, a zero-copy mode and optional JSON output. Note that iperf3 is NOT backwards compatible with the original iperf.

iperf3 is the standard approach for "iperf".

3.22 Security notes Thanks to Claude and Ada Logics for finding and reporting two potential security vulnerabilities. One is a remote use-after-free in iperf_server_api.c (ANT-2026-E5BA80X9 / CVE-2026-101283) and the other is a heap buffer overflow in iperf_auth.c (ANT-2026-FXH14FHV / CVE-2026-101276). Thanks to Justin Stitt for reporting and fixing a heap-buffer overflow was fixed in iperf_auth.c. Thanks to Ravindu Lakmina Munaweera (Github: @Ravi-lk) for reporting and fixing a DOS infinite-loop (CVE-2026-102253). Thanks to Dirk Müller for finding and reporting an issue with test parameters (CVE-2026-71217). The iperf-3.18 release notes were updated to reflect that a code change in that version addresses CVE-2026-71218. Notable user-visible changes …
