The "s" in -Os stands for "size", not for "speed". So if -Os compiled
code-execution is faster than the default CFLAGS, something must be

May-be Gnome has grown too fat, such that it swaps/pages less if its
executables are being -O2 compiled ;).

I think, bringing this to observation to the attention of upstream GCC
(mailing list gcc.gnu.org) would be the appropriate approach.
