If the code Chris gave is too slow, you could:
1. Change it to get an IMP for -objectAtIndex:, then re-test.
2. Change it to use CFArrayGetValueAtIndex(), then re-test.


Those are excellent suggestions.

For the record, I replaced my NSEnumerator with a loop that calls -[NSArray count] once to get the size, then calls -[NSArray objectAtIndex:] for each element. The performance is essentially identical to the loop that uses NSEnumerator (within 1%).
