The FAQ cannot be a treatise on optimizations, because the effect of each
optimization switch depend *heavily* on the program. As I've said
elsewhere, -O3 can make your program slower than -O2 (it surely makes it
larger), and I have real-world programs to prove this. Explaining all
these intricacies will make a good book, not a FAQ.
