If I have a UIImage or CGContextRef or the pure bitmap data (direct access to decompressed ARGB-8 pixels), what’s my best option to blur an image with radius 10 pixels as fast as possible?

Either use a stack blur, a box blur or use the OpenGL texture blur (google the first two, and check the Apple dev samples for the latter).
