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?
