The problem I'm having is I when I use the -w global option on the TCP_STREAM test I get the same throughputs, at least within error, regardlesss of how large or small I set the inter-burst time to. It lets me run the test, adds ":interval" to the end, and runs through without error. When I enable debugging everything looks good except the signal catcher:<br><br>[root@ralph ~]# netperf -H 192.168.100.13 -d -w 100<br>scan_sockets_args called with the following argument vector<br>netperf -H 192.168.100.13 -d -w 100<br>Program name: netperf<br>Local send alignment: 8<br>Local recv alignment: 8<br>Remote send
