Thanks for reporting! You have two results that are somewhat off:

Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz
cycles: out 6500, in 3135

6500 / 3000 = 2.17. Fairly high...

Intel(R) Xeon(R) CPU E5335 @ 2.00GHz
cycles: out 3217, in 1898

3217 / 2000 = 1.61. Okay.

Dual Core AMD Opteron(tm) Processor 275
cycles: out 5508, in 5524

2200 MHz right?

5508 / 2200 = 2.50. Very high.

Nothing was dozing off in some ACPI sleep state or something?
