Hi Florin, I'm not sure why the echo app was crashing on me yesterday, built the debug version, no crash, so I rebuilt the release version and also no crash. For some reason, even though udp-cksum now shows as an active rx offload, the function ip4_local_check_l4_csum is still being called, but I added a return statement right at the top to see how much overhead it really introduces, and it didn't really make a difference, so I'm thinking that is not the bottleneck.
Do you think the rx-miss counter shown below is relevant, and if so, any tips on what that suggests? vpp# sh interface Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count TenGigabitEthernet5/0/0 1 up 9000/0/0/0 rx packets 35702325 rx bytes 42584946555 drops 122 ip4 35702203 rx-miss 16959304 vpp# sh runtime Thread 1 vpp_wk_0 (lcore 22) Time 90.3, 10 sec internal node vector rate 0.00 vector rates in 3.9519e5, out 0.0000e0, drop 4.7598e-1, punt 0.0000e0 Name State Calls Vectors Suspends Clocks Vectors/Call dpdk-input polling 129415453 35702246 0 6.94e2 .28 drop active 43 43 0 1.82e3 1.00 error-drop active 43 43 0 1.47e3 1.00 ethernet-input active 148777 35702246 0 1.93e1 239.97 ip4-input-no-checksum active 148767 35702203 0 3.15e1 239.99 ip4-local active 148767 35702203 0 5.03e2 239.99 ip4-lookup active 148767 35702203 0 4.19e1 239.99 ip4-udp-lookup active 148767 35702203 0 4.34e1 239.99 llc-input active 41 41 0 1.45e3 1.00 lldp-input active 2 2 0 1.73e4 1.00 session-queue polling 100382138 0 0 2.82e2 0.00 udp4-input active 148767 35702203 0 4.01e3 239.99 unix-epoll-input polling 126267 0 0 1.04e4 0.00 Thanks!
