Hi folks,<br><br>I am trying to measure the cpu overhead when the system is sending out packets with certain rates. To control the packets sending rate, I use the following command (by changing -b values):<br><br>" netperf -t UDP_STREAM -H 172.16.2.150 -b 120 -l 300 -w 10 -- -m 1400 -s 256K -S 256K" (12000pkts/sec)<br>
<br>I have to use the packet size as max as possible, so I choose 1400 in this case. <br><br>The problem is that when I increase the -b values, the following error message begin to show up:<br><br>"UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 172.16.2.150 (172.16.2.150) port 0 AF_INET : interval<br>
netperf: receive_response: no response received. errno 4 counter -1"<br><br>What could be the reason of this error message? How should I fix this one and continue with my works or is there any pass away method ?<br><br>
Thanks in advance for any thoughts!<br>Lei<br><br>
