Hi,
We are getting close to releasing iperf 2.0.8. It's been extensively used for
our wi-fi testing as well as a little bit of 10G, but not much. Please feel
free to try it out and contact me about any issues.
https://sourceforge.net/projects/iperf2/
Below are the main differences from 2.0.5
* Fix portability, compile and test with Linux, Win10, Win7, WinXP and
MacOS, (possibly android)
* Improved performance
* Enhanced reporting with -e
* Support smaller report intervals (5 ms or greater)
* Support SO_RCVTIMEOUT for server reports regardless of no packets
* 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)
* Add local port to bind support (-B option) using colon as separator
* (e.g. iperf -c 192.168.100.100 -B 192.168.100.10:6001)
* Support TCP rate limited streams (via the -b) using token bucket
* Support packets per second (UDP) via pps as units, (e.g. -b 1000pps)
* Display PPS in both client and server reports (UDP) (-e required)
* Support realtime scheduler as a command line option (--realtime or -z,
assumes proper user privileges)
* Improve client tx code path so actual tx offered rate will converge to
the -b value
* Improve accuracy of microsecond delay calls (in platform independent
manner)
* (Use of Kalman filter to predict delay errors and adjust delays per
predicted error)
* Display target loop time in initial client header (UDP)
* Fix final latency report sent from server to client (UDP)
* Include standard deviation in latency output
* Suppress unrealistic latency output (-/-/-/-)
* Support SO_SNDTIMEO on send so socket write won't block beyond -t (TCP)
* Use clock_gettime if available (preferred over gettimeofday())
* TCP write and error counts (TCP retries and CWND for linux) (-e required)
* TCP read count, TCP read histogram (8 bins) (-e required)
Thanks,
