--- Comment #16 from Sylvain Galliano <s...@efficientip.com> --- (In reply to Vincenzo Maffione from comment #14) Here are the results: X520 with 1 queue ix0: PCI Express Bus: Speed 5.0GT/s Width x8 ix0: netmap queues/slots: TX 1/2048, RX 1/2048 ******************************************* sysctl dev.ix.0.iflib.nm_tx_tmr_us=0 (default value) pkt-gen: 683.502433 main_thread [2639] 4.215 Mpps (4.227 Mpkts 2.023 Gbps in 1002819 usec) 465.43 avg_batch 99999 min_space ******************************************* sysctl dev.ix.0.iflib.nm_tx_tmr_us=300 pkt-gen: 750.688608 main_thread [2639] 6.496 Mpps (6.646 Mpkts 3.118 Gbps in 1023000 usec) 465.45 avg_batch 99999 min_space ******************************************* sysctl dev.ix.0.iflib.nm_tx_tmr_us=200 pkt-gen: 771.736855 main_thread [2639] 8.907 Mpps (9.112 Mpkts 4.275 Gbps in 1022999 usec) 465.45 avg_batch 99999 min_space ******************************************* sysctl dev.ix.0.iflib.nm_tx_tmr_us=100 pkt-gen: 804.554603 main_thread [2639] 14.136 Mpps (14.147 Mpkts 6.785 Gbps in 1000748 usec) 465.45 avg_batch 99999 min_space -> close to 10G line rate ******************************************* sysctl dev.ix.0.iflib.nm_tx_tmr_us=90 pkt-gen: 872.156329 main_thread [2639] 14.880 Mpps (15.054 Mpkts 7.142 Gbps in 1011721 usec) 466.96 avg_batch 99999 min_space Now using same X520 NIC using 4 queues. ix1: PCI Express Bus: Speed 5.0GT/s Width x8 ix1: netmap queues/slots: TX 4/2048, RX 4/2048 ******************************************* sysctl dev.ix.1.iflib.nm_tx_tmr_us=0 (default) pkt-gen: 047.988586 main_thread [2639] 13.596 Mpps (13.623 Mpkts 6.526 Gbps in 1002002 usec) 443.03 avg_batch 99999 min_space -> close to max speed (thanks to 4 queue) ******************************************* sysctl dev.ix.1.iflib.nm_tx_tmr_us=400 pkt-gen: 094.224581 main_thread [2639] 14.887 Mpps (14.904 Mpkts 7.146 Gbps in 1001173 usec) 440.75 avg_batch 99999 min_space Looks really good for X520 NIC whatever the number of queue I used.
