No, i worried about the " (IRQs *7)" format. I never seen this before....
I searching the bottleneck of my system, and simply found these lines.
I have another question:
CPU0 CPU1 CPU2 CPU3 0: 112 0 0 12095059 IO-APIC-edge timer 8: 0 0 0 2005 IO-APIC-edge rtc 9: 0 0 0 0 IO-APIC-level acpi 14: 0 0 0 1922693 IO-APIC-edge ide0 169: 0 0 0 0 IO-APIC-level uhci_hcd:usb2 177: 0 0 0 0 IO-APIC-level uhci_hcd:usb3 185: 0 0 0 0 IO-APIC-level uhci_hcd:usb4 193: 0 0 0 0 IO-APIC-level ehci_hcd:usb1 209: 0 0 0 204795144 IO-APIC-level eth0 217: 0 0 0 424538586 IO-APIC-level eth1 NMI: 0 0 0 0 LOC: 12095010 12095009 12094905 12094904 ERR: 0 MIS: 0
How can i avoid this? (all irq on CPU 3)
The echo /proc/irq/#smp_affinity # >smp_affinity
Has no effect. :-(
I tried it with kernel irq load balancing is on and off. But nothing is changed. :(
Thanks
