Now, I believe that Saturn will do this, but I believe that does not
work on Intel. Is this correct?
As I understand it, Shark has something called Function Trace, which
will probably do what I want, but that does not appear to be
compatible with Intel either.
The CHUD tools - which both Saturn and Shark are components of - do,
in fact, work on Macs with Intel processors. Be sure you're using the
latest release of Xcode and the latest release of CHUD.
I'd probably start first with Shark to get the most accurate picture
of what my code is doing and where the bottlenecks are. A Shark trace
using "Time Profile (All Thread States)" of either a specific process
or all processes is a great way to see exactly where the CPU time in
your code is being spent, which a purely function-based approach may
not tell you.
