Hi Can I allow to process interrupts from re0 by multiples CPUs I get one CPU overload while other idle last pid: 14902; load averages: 1.92, 2.12, 1.96 up 0+17:47:31 19:59:04 226 processes: 12 running, 197 sleeping, 17 waiting CPU 0: 0.6% user, 0.0% nice, 1.2% system, 88.3% interrupt, 9.8% idle CPU 1: 1.8% user, 0.0% nice, 29.4% system, 0.0% interrupt, 68.7% idle CPU 2: 3.7% user, 0.0% nice, 30.7% system, 0.0% interrupt, 65.6% idle CPU 3: 3.1% user, 0.0% nice, 25.8% system, 0.0% interrupt, 71.2% idle Mem: 264M Active, 1641M Inact, 272M Wired, 832K Cache, 112M Buf, 1721M Free Swap: 4096M Total, 4096M Free PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND 12 root -92 - 0K 152K CPU0 0 354:30 96.78% {irq256: re0} 11 root 155 ki31 0K 32K RUN 1 929:16 77.83% {idle: cpu1} 11 root 155 ki31 0K 32K RUN 3 922:41 72.95% {idle: cpu3} 11 root 155 ki31 0K 32K RUN 2 904:02 71.63% {idle: cpu2} 13 root -16 - 0K 32K CPU3 1 71:11 18.65% {ng_queue1} 13 root -16 - 0K 32K RUN 1 71:10 18.36% {ng_queue3} 13 root -16 - 0K 32K RUN 3 71:18 17.63% {ng_queue0} 13 root -16 - 0K 32K RUN 1 71:11 17.14% {ng_queue2} 11 root 155 ki31 0K 32K RUN 0 682:25 10.55% {idle: cpu0} 55709 root 20 0 13408K 5840K select 2 15:50 1.71% snmpd 14902 cacti 33 0 11960K 3480K select 1 0:00 1.12% snmpget 14864 cacti 46 0 11116K 2836K piperd 3 0:00 1.12% perl5.10.1 14867 root 46 0 9728K 1956K select 3 0:00 1.12% sudo I have try to tune system how described on this: https://calomel.org/network_performance.html but that did not help. Can you advice me something, to allow process interrupts by all CPUs? -- С уважением, Коньков mailto:kes-kes@yandex.ru
