Auto mode (-A) should throttle down the CPUs when they've been idle for a couple ticks. If they're not doing that, then maybe something else is wrong that's causing excessive interrupts or otherwise keeping the CPUs from going idle. What's the output of "vmstat -i" look like? What processes other than 'idle#' are burning CPU on "top -HS"? Philip Guenther
