Hi, Could you provide a bit more info about the numbers you are seeing and the type of test you are doing? Also some details about your configs and vpp version?
As for tcp_tw_recycle, I believe that was removed in Linux 4.12 because it was causing issues for nat-ed connections. Did you mean tcp_tw_reuse? If yes, are you testing CPS with only one remote client IP?
