Performance differences with IRQ_ALL_CPUS

2009-04-21 Thread Subodh Nijsure
Hi, I have board with MPC8572E (dual core PPC). I have one board running kernel with IRQ_ALL_CPUS set to Y and another with that option turned off. Kernel version #2.6.26 With IRQ_ALL_CPUS turned off ( Here interrupts all go to CPU0 ) hdparm -tT /dev/hda /dev/hda: Timing cached reads: 3048
