Thanks for the update, I tested v5 on main (84b3e4555a1f) and the regression we previously saw no longer reproduces. Will the patch be backported to 20.11? I can still reproduce a 2% drop in single core packet forwarding performance with v4 applied on v20.11.3. Testpmd: dpdk-testpmd -n 4 -a 0000:82:00.0 -a 0000:82:00.1 -c 0x9000 -- -i --nb-cores=1 --txd=256 --rxd=256 --auto-start Traffic generator is TREX with pattern (Ether / IP / UDP). Drop is from ~50.5 mpps to ~49.5 mpps. OS: 18.04.5 LTS Device: ConnectX-5 MLNX_OFED: MLNX_OFED_LINUX-5.4-1.0.3.0 Firmware: 16.31.1014 Regards, Ali
