We need to investigate it, and share more data once we have it.

Then 51-54 are used for ports.<o:p></o:p> The one thing I see here is that you define a lcore.port mapping of -m “52.1” meaning lcore 52 and port 1. You only have 1 port, which means it should be -m “52.0” the other unused lcores will be reported as not used. Looks like I need to add some tests to detect this problem. ☹<o:p></o:p> <o:p> </o:p> I hope this helps.
