Hi,
I noticed that the latest editions of RedHat EL 4.3 and direct
descendants today need a program called irqbalance to activate
true SMP IRQ load balancing for your machine's hardware.
If one boots a SMP kernel (2.4.xx or 2.6.xx) kernel on a machine
which either has 2 or more physical CPU's (also dual-core CPU's)
, and one does not start up the irqbalance util from the
kernel-utils package ( see e.g.
There is an in-kernel IRQ balancer. Redhat just choose to turn it
off, and do it in userspace instead. You can re-enable it if you
compile your own kernel.
