This doesn't mean anything. Can you please provide concrete numbers (what you experience) and what is your expected target? Because I do not have such problematic experience.

Even if morphic took 40 ms and Spec 100 ms to open a window, then it's a non-priority problem (~100ms to open a medium-sized window is a non-issue). Unless you are opening such windows every minute���

Also I am a bit afraid that the slowness would come from the layout processing / composing the objects��� which is a really complex piece, and right now our priority is cleaning up the user-facing API.

But at least we can think about it, whether we would be able to do something about it now or not.
