If you were offended by my comments I most humbly apologize. I hope you can
understand the irony of someone named Dell talking about building their own
computer from as near to scratch as possible. May I be both impressed and
amused? ;-) Once upon a time I could have built a system from scratch but
not anymore; Not with surface mount components & ball-grid sockets and > 1.0
GHz traces on the motherboard, etc. The last system I boot strapped from
solder was a 20 MHz Z280 and that was over 20 years ago. These days I'd
rather just go down to Fry's and boot strap an OS from the BIOS up. Hardware
is just too hard for me these days. ;-)

Before you take offense again I'm asking in all seriousness: "Did you press
the 'start' button?". Did you attach to your running process or did you
select "Launch using performance tool: SHARK" from Xcode's "Debug" menu?
FYI: There are also API's that you can use to turn SHARK profiling on/off
directly from your code. So if you have a specific routine that you want
performance info on you can focus SHARK's sampling.
