Hello,
I have strange problem, my system has two 12-core procesors, when
setting smp_affinity and rps_cpus to spread load accros all cores, I
get following:
ethtool -S S8P0 |grep -E "rx.*pack"
rx_packets: 28059349668
rx_fcoe_packets: 0
rx_queue_0_packets: 1739671933
rx_queue_1_packets: 1740406739
rx_queue_2_packets: 1945709824
rx_queue_3_packets: 1741279872
rx_queue_4_packets: 1739593471
rx_queue_5_packets: 1740392727
rx_queue_6_packets: 1740513001
rx_queue_7_packets: 1740921491
rx_queue_8_packets: 1741525459
rx_queue_9_packets: 1739646341
rx_queue_10_packets: 1741068593
rx_queue_11_packets: 1741374592
rx_queue_12_packets: 1739709430
rx_queue_13_packets: 1747586478
rx_queue_14_packets: 1740398506
rx_queue_15_packets: 1739546993
rx_queue_16_packets: 690
rx_queue_17_packets: 455
rx_queue_18_packets: 653
rx_queue_19_packets: 411
rx_queue_20_packets: 510
rx_queue_21_packets: 514
rx_queue_22_packets: 588
rx_queue_23_packets: 431
but for tx:
ethtool -S S8P0 |grep -E "tx.*pack"
tx_packets: 23697264990
tx_fcoe_packets: 0
tx_queue_0_packets: 897068903
tx_queue_1_packets: 897204633
tx_queue_2_packets: 1705630673
tx_queue_3_packets: 897124425
tx_queue_4_packets: 897124753
tx_queue_5_packets: 897114279
tx_queue_6_packets: 897379101
tx_queue_7_packets: 897218157
tx_queue_8_packets: 904811070
tx_queue_9_packets: 897124394
tx_queue_10_packets: 901837638
tx_queue_11_packets: 897419500
tx_queue_12_packets: 1241034979
tx_queue_13_packets: 1247080319
tx_queue_14_packets: 1247499026
tx_queue_15_packets: 1240739566
tx_queue_16_packets: 891720194
tx_queue_17_packets: 891610281
tx_queue_18_packets: 891814848
tx_queue_19_packets: 891770115
tx_queue_20_packets: 891746387
tx_queue_21_packets: 891680822
tx_queue_22_packets: 891775521
tx_queue_23_packets: 891735428
Can You provide some clue to spread rx_queue for all cores not only
first 16 ?
