--- Comment #3 from Nathan Sidwell <nathan at gcc dot gnu.org> --- yeah, I'm not surprised by these numbers. IIUC the linear search happens when we get a qualified lookup during parsing. Unqualified lookup will find the IDENTIFIER_VALUE binding. But ICBW. Anyway, when I tried to fix this piece, I kept running into a wall, due to the way we try and make all bindings behave somewhat as-if a regular local-scope binding. Which is why I ended up punting. See my gcc cauldron name-lookup talk. One bit we could change is keep the MEMBER_VEC sorted during construction. That holds member functions during that time. We'd still need to do the linear field lookup though, to find non-function members. Patch for this on the name-lookup branch.
