Hi Jeremy, I try reproduce your result and then fix the issue, but I do not reproduce it yet.
I run at netperf-2.6.0 at one machine as server: netserver, other machine: netperf -t TCP_RR -H $SERVER_IP -l 60. The target machine is used in both client and server. I do not reproduce the performance drop issue. I also notice the result is not stable, sometime it is high, sometime is low. In sumarry, it is hard to make a definite result. Can you try tell me how to reproduce the issue? how do you get the C0 data? What's your config for kernel? Do you enable CONFIG_NO_HZ_FULL=y or only CONFIG_NO_HZ=y?
