https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D248652 --- Comment #2 from Sylvain Galliano <sg@efficientip.com> --- Hi Vincenzo, thanks for your quick reply. I've disabled all offloads in both 11-STABLE and CURRENT and I got the same results. I did another test that may help you: I've recompiled pkt-gen on current after adding: #define BUSYWAIT Testing NIC Intel X520, 1 queue configured default pkt-gen: 696.194470 main_thread [2641] 2.560 Mpps (2.570 Mpkts 1.229 Gbps in 1004000 usec)=20 465.45 avg_batch 99999 min_space with busywait: 733.764470 main_thread [2641] 14.881 Mpps (15.172 Mpkts 7.143 Gbps in 10195= 65 usec) 344.22 avg_batch 99999 min_space 14Mpps, same as 11-STABLE --=20 You are receiving this mail because: You are the assignee for the bug.
