Well, that is sort of what we did and how we found out we need this
performance information.
Personally, I also prefer to think in advance about the potential
bottlenecks and performance issues in order to avoid unnecessary
re-engineering efforts. Granted, Apple's data structures are
professionally designed, optimized, and so on...not to mention the
convenience of having the work done for you...but I'd rather have some
idea (in advance of architecting and writing code) of what I am getting
into performance-wise. I suppose there are others out there who may
also wonder whether to use third-party libraries or to write their own,
especially in these situations in which performance is critical.

Benchmarks are useless anyway.
First write a version of your app that works. Then profile it with
Shark, and optimize wherever that tells you the bottlenecks are. It's
pointless to try to guess where bottlenecks *might* be, when it's so
easy to determine precisely where they *are*.
