Sure ! This is already a quite good point !

I'll have a second look at Apple pages. But from what I've seen most of
the
tools (Shark, CHUD etc.) are oriented toward serial codes.
I do not know much about how to analyze the communications and
interfaces performances.

Thanks again, and thank you for providing us such useful tools !
