Double Compile system and world on gentoo

emerge -e system && emerge -e system && emerge -e world && emerge -e world
This is a command you see mentioned alot by Gentoo monkeys. They say to use it after every update of GCC, any library you might use and glibc. They argue that compiling and recompiling everything like this will optimize the system alot more because you are recompiling the entire system (gcc, glibc etc) with nativly compiled versions of themselves. Same goes for all libraries etc. I doubt the difference in working speed is really worth the hours and hours you end up having your computer compile the same stuff again and again though.
