It might even be faster under ARC since I think the compiler can optimize some retain/release calls. I think the ARC retain and release may be faster than -retain/-release, but I'm not sure about that.

Overall, yes, it's less smooth to include non-ARC code in an ARC project.

I was under the impression that ARC simply inserts the retain/releases into the code essentially write before the compile, so in theory would be equivalent.

ARC inserts the retain/release calls but once that is done there is an additional step where duplicate retain/release pairs are eliminated.
