Hey Abhinav,
We've taken a different tack with DTrace: rather than optimize the
data flow
from kernel to user-land, we've given the user primitives to prune and
accumulate data as close to the source as possible to minimize data
flow and
present the user with a concise answer.
May I ask
Hi Adam,
Ok I understand your point.The user space primitives like aggregates
etc help prune and accumulate data.
I am looking at dtrace from the performance point of view.The idea is
to look at various parts of dtrace,find potential places of
optimization and see if anything can be
