I'm wondering if you're not looking at totally different issues.

For example, if I recall correctly, David had a big hit on the hrtimers.
And I wonder if perhaps Ingo's numbers are without hrtimers or something?

The other possibility is that it's just a sparc suckiness issue, that
simply doesn't show up on x86.
