Hi,
The delay accounting infrastructure has been part of the mainline kernel
for sometime now. From what I've heard from customer-facing people, it
is a great tool to determine where the performance bottlenecks are.
See Documentation/accounting/* for more information about this
infrastructure.
Combining this feature with the features SystemTap currently provides
would be a good thing. Would it therefore be possible to add support for
this infrastructure in SystemTap?
