With your settings, blurring will be x slower compared to directly copying the image.

Blur The standard deviation σ of the Gaussian blur, in pixels..

Gaussian cutoff When to cut off the Gaussian, in multiples of the standard deviation σ ("blur radius"). The Gaussian continues infinitely, but it also drops close to zero fairly quickly, so we can cut it off at some point.

Resolution The number of pixels to skip by for a faster blur. This works best if nearby pixels are similar in color; otherwise, a grid pattern can appear.
