Alistair,

Using multiple CPU's isn't going to help much in your case. The way that works is to use a CPU for a single pipeline iteration. So while this effectively increases your throughput it still takes the SAME amount of time for a single image ... you just get 4x number of images being processed using more CPUs. Instead I'd focus on using some other module than flood fill or increase the speed by using its "fast mode" or reducing the image size (that will 4x decrease the processing time for a single image!) before using the flood fill. The trick is to look for ways to increase the processing using heuristics rather than brute force CPU processing.
