A few random thoughts:
Any chance the RAID is still rebuilding.
Is slow unit truly slower, that is does it take longer as YOU measure
it to do a significant task. I ask because a bad clock will would make
it report longer times due to time measurement errors.
A comparison of the actual number of interrupts (cat /proc/interrupts)
on both machines after they have been up for similar periods, doing
similar things may give a hint as to who has 'stolen' your CPU.
