Also if you are not running over a path that is jumbo-frame clean, try setting -l to something that will fit inside the path MTU. You are receiving this because you commented. I am observing the same problem running UDP tests for different packet sizes and different number of streams.

It's been over a year since this packet loss problem was reported. I've also tried to change the UDP datagram size to match that of iperf2, but this had no effect. What was interesting is that when reversing the test, there's no packet loss. I've come across a similar issue where iperf3 has huge packet loss while iperf2 has none. Tested with latest version as of 20 Jan 6bd4e25 and found that whilst the -w command option can impact the performance somewhat, I can never get it beyond the 10mbit limit. Usually we've seen that multi-Gbps tests, however. At ESnet we have somewhat counterintuitively found that setting larger socket buffers helps reduce losses with UDP tests. The test done previously with iperf2 verified that the tunnel was capable of doing over Mbits UDP as well, so based on iperf3's TCP results and iperf2's UDP results, I'm pretty comfortable that the tunnel itself is operating as expected. We have seen some odd effects related to processor affinity but they usually show up at much higher bitrates than what you're doing i. CPU affinity should make no difference, give that the test machines have only a single CPU, so it's unclear why this is making any effect. What is particularly weird is that I can work around the performance issue by setting the -A parameter CPU affinityas soon as this is done, UDP performance is back to normal. I believe I've found a bug in iperf3 where the performance of UDP tests seem capped at around 10mbit when done over a Linux tunnel interface. рџµДЄlready on GitHub? Sign in to your account.

Description This app is an iOS port for iperf3, which is the most commonly used network testing and performance computation tool. Compatible with iPhone, iPad, and iPod touch. If you click on the info icon at the top left corner, you will find a brief statement regarding the IPERF version issue. Very handy tool to test your network condition. Also nice that you can add custom commands to it too. The app has worked perfectly from day one. It is not like asking for service discovery. Fixed a bug that the device's IP won't be shown on the Server Mode view. And it may have some minor issues with the other iperf3 versions. Priority: 5.This app is an iOS port for iperf3, which is the most commonly used network testing and performance computation tool. Iperf Brought to you by: bmahjduganmitchkutzko. Are you asking how the servers have been started. What do you mean with settings for the server. I assume there is a bug within the iperf software, not shutting down after '-t' seconds if the connection is buggy. I do not know what causes the several iperf processes to stop at February 20th On the local system there have been no indications that couldhave caused these process endings. So a timer should be set to at least stop after e. If there is a problem, iperf shopuld stop after at least the time specified via the '-t' option, i. In the meantime others do not have any problems see e. As you see from the logs some iperf processes stay for several days before they stop, though they should stop after 10 seconds.

I have made a crontab entry to start iperf every day once.
