Download IPerf2 2 for Windows 7, 8, 10, 11 - A tool that measures TCP and UDP performance with metrics around both throughput and latency using network sockets
IPerf2 is a network traffic tool for measuring TCP and UDP performance with metrics around both throughput and latency. The goals include maintaining an active iperf code base across a broad set of platforms and operating systems. This is a multi-threaded design which scales with the number of CPUs or cores within a system.
About iperf 2 and iperf3: Read about the differences between these programs.
Features of IPerf2:
- TOO MANY TO LIST SEE THE RELEASE NOTES OR THE MAN PAGE!!
- Fix portability, compile and tested with Linux, Win10, Win7, WinXP, MacOS, Android and some set-top box OSs.
- Require -u for UDP (-b no longer defaults to UDP)
- Improved performance
- Enhanced reporting with -e
- Support smaller report intervals (100 us or greater, configure --enable-fastsampling for high precision interval time output)
- Support SO_RCVTIMEOUT for server reports regardless of no packets
- Support SO_SNDTIMEO on send so socket write won't block beyond -t or -i
- Support SO_TIMESTAMP for kernel level packet timestamping
- Support end/end latency in mean/min/max/stdev format (UDP) (-e required) (assumes client and server clocks synched, e.g by Precision Time Protocol to an OCXO oscillator per Spectracom)
- Fixes to bind so OS can auto assign source port
- and more...
