     What about the rest of the system?  Run some simple cpu benchmarks.
     If those are slow also this could be an indication of an interrupt
     storm (and possibly even a SMI storm, similar to ruse39's issue).
Do you have a suggestion for such a cpu benchmark?

vmstat -i looks okay:

# vmstat -i
