A DTrace script will serve you a lot better than Shark. Shark does statistical profiling. If you take a time profile using Shark, all it does is periodically (every millisecond, by default) interrupt your application and check to see what it's doing. From this it assembles a picture of where your app is spending its time. This is obviously not guaranteed to see every message-send that happens: some very short-running ones might just happen to occur between two Shark interruptions, every time, and Shark will never see it. With DTrace, you can automate collecting data *every* time objc_msgSend is called, with perfect reliability. (Instruments is backed by DTrace, for an idea of the scope of capabilities DTrace has.)
