     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).
I did some primes calculation with

> /usr/bin/time -h primes 1 4242424242 >/dev/null

and they finished on same time with acpi interrupt routing enabled/disabled.
