did you have a look at the Bloom training course from our SDK? In there we optimize the amount of texture fetches by using the filtering capabilities of the texture units. If your filter coefficients allow it, then you can save quite a few texture lookups that way.
Do you require a 11×11 kernel to downsample your image? You will be most likely bandwidth bound depending on your input image size.
