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.

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
