Hi Matt, thanks. The *no-multi-seq* option is actually dropping the performance even more. Once enable it drops from 5 Mpps ( out of expected 10 Mpps) to less than < 1 Mpps. Therefore I disabled the option again.
The dpdk applications foward the full 10 Mpps without any dev-args: > > ./dpdk-l2fwd -n 4 -l 6 -a 0000:4b:00.0 -a 0000:4b:00.1 -- -q 2 -p 0x3 but also adding those options confirm the full 10 Mpps. Either way *l2fwd* will not drop any packets and run the full load. > > ./dpdk-l2fwd -n 4 -l 6 -a > 0000:4b:00.0,mprq_en=1,rxqs_min_mprq=1,mprq_log_stride_num=9,txq_inline_mpw=128,rxq_pkt_pad_en=1,dv_flow_en=0 > -a > 0000:4b:00.1,mprq_en=1,rxqs_min_mprq=1,mprq_log_stride_num=9,txq_inline_mpw=128,rxq_pkt_pad_en=1,dv_flow_en=0 > -- -q 2 -p 0x3 Contrary by using the default */etc/vpp/startup.conf* options of DPDK I only yield 4 Mpps out of 10 Mpps expected. Once I added the devargs *mprq_en=1,rxqs_min_mprq=1,mprq_log_stride_num=9,txq_inline_mpw=128,rxq_pkt_pad_en=1,dv_flow_en=0* it gained another 20% ( as recommended in DPDK mellanox perf-report )
