Asterisk & SMP: Is irqbalance Redundant on 2.6 Kernels?
...of the interrupts were being handled by CPU0. Apparently, SUSE's
kernels are compiled without IRQ balancing enabled.
I've also done a little digging through "kernel-parameters.txt" and I
came across a few interesting lines:
acpi= noirq -- do not use ACPI for IRQ routing
acpi_irq_balance [HW,ACPI] ACPI will balance active IRQs -- default
in APIC mode
pci= noacpi [IA-32] Do not use ACPI for IRQ routing or for PCI
scanning.
noapic [SMP,APIC] Tells the kernel to not make use of any
IOAPICs that may be present in the system.
noirqbalance [IA-32,SMP,K...

Performance problem on a linux bridge used for shaping.
Hello,
Here is the situation. There is a machine with 3 intel gigabit card, 2
of them on PCI-X and in bridge, the 3rd is used only for management
access. The machine is a dual Xeon 2.8GHz with HT. With 2.6.8 kernel
from debian (testing) and htb with u32 on, i usually get about 30-40%
software interrupts on CPU0 and CPU2, and without htb and u32, 10% less.
Now, if I boot with 2.6.17.9 kernel,
