This is sort of an uninformed question, in that you don't seem to know the difference between Core Image, OpenGL (which you didn't mention, but undoubtedly meant). and Metal (there is no Quartz Composer API).
Anyway, if you're looking for the absolute fastest performance from a Quartz Composition, use OpenGL (correctly) within a Core Image patch and/or OpenCL with its respective patch. There is no faster than either—not even Metal.
