Not necessarily. Back in the day I generated thumbnails for lots (and lots) or very large images and getting the best performance is tricky. Most of the time running multiple processes just ends up causing massive context switching and slowing down the whole thing. Even multithreading turns out to be bad, most of the time. I got the best performance by forcing GraphicsMagick to use a single thread and spinning up multiple operations. I wonder how this app would deal with something like that.
