It also seems to depend on the GPU hardware. Googling for "CILanczosScaleTransform slow" produces many hits. Suggested workarounds are to use CIAffineTransform if you're willing to accept a lower quality result. Apparently CILanczosScaleTransform is rather slow since it produces a high quality result.
