Hi, From the Description of irqbalance, it is supposed to balance IRQ activity between two or more processors. On /etc/init.d/irq_balancer LINE 41 there is the following line if [ $PHYS -gt 1 -o \( $PROC -gt 1 -a $PHYS -eq 0 \) ] ; then witch explicitly states that the $PHYS variable has to be greater then one. This means that there has to be two physical processors, and the daemon will not load if the computer has either a Hyper-Threading or Dual-Core CPU. I'm sure that SuSE folks dis this on purpose but, is it possible to someone to tell me why irqbalance will not work on this CPU's, specially on a Dual-Core System ? I've done a goggling on the subject and find nothing substantial on this subject. My system is a Dual-Core Intel(R) Pentium(R) D CPU 3.20GHz Thanks for your time -- Rui Santos http://www.ruisantos.com/ They that would give up essential liberty for temporary safety deserve neither one of them.
