  • Comment: CVS: bandwidth is printed using wrong printf directive

    Looked again the Locale.c source and I can surely say my patch is faulty. But the bug is still valid.

  • CVS: bandwidth is printed using wrong printf directive

    In reposrtCVS.c file (iperf v 2.0.5) on function CSV_stats( Transfer_Info *stats ) bandwidth is printed in following way: max_size_t speed = (max_size_t)(((double)stats->TotalLen * 8.0) / (stats->endTime - stats->startTime)); /* max_size_t speed is uint64_t */ /* ... */ printf( reportCSV_bw_format, timestamp, (stats->reserved_delay == NULL ?...

  • Link to iperf version 3

    Since iperf version 3 has active development and is a continuation of this project the new site should be linked to from http://iperf.sourceforge.net/ http://sourceforge.net/projects/iperf/.

  • Comment: 2.0.5 produces less UDP than 2.0.4

    Hello, would you like to mention your test hardware or more test details? For example, the command line arguments with which you run the tests would be of great help. To add some comments wrt performance: I've managed to reach more than 7.0Gbit/sec with iperf 2.0.4. I'd be greatly surprised if there was such a big performance drop between 2.0.4 and 2.0.5. Best Regards, Leonidas Tsampros.

  • Comment: iperf hangs intermittently

    What do you mean with settings for the server. Are you asking how the servers have been started. Here it is: ..../bin/iperf -w12000K -s -o /var/log/iperf-T.log -p 5001 -D ..../bin/iperf -u -s -o /var/log/iperf-U.log -p 5001 -D Regards Ralph.

  • iperf hangs intermittently

    I am using iperf to test bandwidth between different unix derivates. Starting an iperf with the command : iperf -i1 -t10 -w2000K -M 536 -c 195.83.184.4 somtimes works correctly, sometimes hangs, I have made a crontab entry to start iperf every day once. As you see from the logs some iperf processes stay for several days before they stop, though they should stop after 10 seconds. In...
