[Xen-users] irqbalanced on SMP dom0 ?

[Stephan Seitz <s.seitz@xxxxxxxxxxxx>]

Hi listmembers,

not a really urgent question, but i'm just curious about it:

Is it advised to use an irqbalanced on dom0 when running
domU's pinned to particular cores?

as an example, i've got a dual quadcore xen system running
with
        domU pinned to cores 1-3 (CPU#0)
        domU pinned to cores 4-5 (CPU#1)
        domU pinned to cores 6-7 (CPU#1)
so dom0 should have 100% time on core 0 (CPU#0).

When looking at /proc/interrupts, all peth and arcmsr (areca raid)
interrupts - said: all IO - are handled by CPU0.

Should i use irqbalanced to use other cores as well?

Any suggestions are really welcome!

Thanks in advance.

Stephan
