The –D option works well in most cases, but when sending UDP data from netperf to netserver the reports show how much data is being sent from netperf, not how much data is actually making it through the network to netserver. There can be a significant difference between the two numbers. I have attached a patch which changes the behavior so that on an OMNI UDP send test information is sent periodically from netserver to netperf indicating the actual throughput. Netperf then displays the interval results based on the received data instead of the sent data.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Please take a look at the patch and let me know what you think.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards,<o:p></o:p></p><p class=MsoNormal>Jonathan Cook<o:p></o:p></p><p class=MsoNormal>Electronics Engineer<o:p></o:p></p><p class=MsoNormal>National Institute of Standards and Technology<o:p></o:p></p></div></body></html>
