You probably got too old kernel, I submitted an optimisation some time ago
that optimised scanning of empty blocks. Before that optimisation it was
slower to mount an nearly empty FS than it was to mount a almost full FS.

Summary didn't help me either and summary might slow your
mount down as it cannot make nodes obsolete on flash.
