At a guess, I would expect kwm to be faster, but probably less far along than Amethyst in terms of features/stability.

It's been a long time since I've actually written any C++, but briefly looking through the code it looks like it's making some of the same assumptions I made that resulted in some strange problems like the dreaded fullscreen bug (https://github.com/ianyh/Amethyst/issues/254). That said, some of those assumptions were made 3 OS X versions ago so things might have improved.

It does, however, look a lot lighter weight than Amethyst is, and it looks like it does a better job at aggressively caching. It also supports binary space partitioning, which Amethyst doesn't support yet (https://github.com/ianyh/Amethyst/issues/255). If I'm reading it correctly, though, that's the only thing it supports.

All in all, it seems like a great project. We could probably learn some things from each other, and I expect both projects would be the better for it.
