My bad. :( I was reading the metric list wrong.

I'm not aware of any such data. It seems Linux is rather short on some useful
metrics that other Unix flavors have. This would be a major improvement in
Linux. It could surpass other Unix flavors in this arena if there was motive
force in the kernel development core.
If anyone has influence on kernel development, please contact the appropriate
people! I understand that Linus is not big on instrumentation. Don't know
if that's true or not, just something I heard somewhere.
Cordially,
Scott
