The last two steps are needed to produce a static executable. It appears that for FreeBSD (tested on FreeBSD 11.1-RELEASE), only Necessary to pass the -without-sctp flag at configure If SCTP is installed on the system it might also be For iperf-3.8 or later, configuring as configure -enable-static-bin is another, shorter way to accomplish Generation of shared libraries and link the executable If OpenSSL is installed, be sure that its static libraries areĪlso installed, from the openssl-static package.īe sure that lksctp-* packages are not installed, becauseĪs of this writing, there do not appear to be any staticĬonfigure iperf3 thusly: configure "LDFLAGS=-static" -disable-shared These options are necessary to disable the If necessary, install the static C libraries for CentOS this is
The steps below have nominally been tested on CentOS 7.4, butĬan probably be adapted for use with other Linux distributions: There are a number of reasons for building an iperf3 executable with
How can I build a statically-linked executable of iperf3? Some community-provided binaries of iperf3 for Some people are using Cygwin to run iperf3 in Windows, but not all Iperf3 is not officially supported on Windows, but iperf2 is. I’m trying to use iperf3 on Windows, but having trouble. If you want to use multiple iperf3 streams use the method described here. Recommend using iperf2 for parallel streams. Iperf3 is single threaded, and iperf2 is multi-threaded. iperf3 parallel stream performance is much less than iperf2. We recommend being familiar withīoth tools, and use whichever tool’s features best match your needs.Ī feature comparison of iperf2, iperf3, and nuttcp is available at: iperf2’sĬurrent development is focused is on using UDP for latency testing, as wellĪs of this writing (2017), both iperf2 and iperf3 are being actively iperf2.0.8, released in 2015, made iperf2 a useful tool. Problems with iperf2, and added a number of new features similar to Then in 2014, Bob (Robert) McMahon from Broadcom restarted Many of the feature requests for iperf3 came from the Threaded, and not worry about backwards compatibility with For this reason, it was decided to make the tool single Tool as simple as possible, so others could contribute to the codeīase. Was needed, and began development of iperf3. Iperf2’s problems, ESnet decided by 2010 that a new, simpler tool Iperf2 was orphaned in the late 2000s at version 2.0.5, despite some Iperf3 FAQ ¶ What is the history of iperf3, and what is the difference between iperf2 and iperf3?
