Whilst the OS is different, there isn't that much difference in memory management algorithms and CPU schedulers. It's the same basic research and theory that goes into that fundamental level stuff.
On top of that there are bigger differences - approaches to building OS functionality. But that /shouldn't/ affect how quickly Photoshop applies a filter. The filter code is from Adobe in both cases, and the actual work is done by the CPU, with stuff stored in RAM, and rendered by a GPU.
