It's inconsistencies like these that make me suspicious of the > whole set of results :/ I got the number after a reboot, not sure what happened. And I also feel surprised... But the result shows the number, so I have to put it here. > > Are you getting these numbers from ethtool_stats.pl or from the XDP > program? What counter are you looking at, exactly? For bridge testing I use ethtool_stats.pl. For later xdp_redirect_map and xdp_redirect_map_multi testing, I checked that ethtool_stats.pl and XDP program shows the same number. When run ethtool_stats.pl the number will go a little bit slower. So at the end I use the xdp program's number. I'm going to re-setup the test environment and share it with you. Hope we could get a final number that we all accept. Thanks Hangbin
