You're welcome to try it out, but it isn't supported. GCC has a few obscure misfeatures at -O3. Some applications break at -O3, usually because they violate C's aliasing rules or contain broken inline assembly. At one point, the kernel's TCP checksum code had some difficult-to-solve problems with -O3, and I'm not sure whether that has been fixed. Despite all of that, I built world and kernel with -O2 a while ago and noticed no problems whatsoever. Just note that you've been warned, and you probably won't see a significant performance improvement anyway.
