So I guess you agree that this is actually an argument against this Change,=
is it not?=C2=A0

=C2=A0Yes it is, unless da= ta shows shows otherwise, which I have not seen.


Co= nsidering that, since profiling is usually not done on battery,
improving the performance of profiling at the expense of overall performanc= e
is not a win when you consider the battery use.

(The position of your reply in the thread was not optimal, because you
answered a mail that was talking about the performance of profiling, not th= e
overall performance of the system. So that made it easy to misinterpret you= r
position.)

Sorry for that, traveling and re= sponding on mobile.
=C2=A0

=C2=A0 =C2=A0 =C2=A0 =C2=A0 Kevin Kofler
