At Blackboard we developed yet another DnD library only because existing react solutions were not accessible - https://github.com/blackboard/react-dnd-ax . But unfortunately it is not quite "performant".
Since then I found another promising library which while not fully accessible, provides great deal of keyboard interaction (last time I checked it in February - library is under very active development) - https://github.com/atlassian/react-beautiful-dnd
We are still on a lookout for well performing solution for react, yet fully accessible..
Before I implemented this one the closest candidate for my app was react-beautiful-dnd but currently is does not support "copy" behavior which I need. react-beautiful-dnd relies on react-motion for animations and beside a bigger bundle size, to my experience css hardware accelerated transformations provides more performance. Try them under chrome 6x slowdown performance
Was your performance issue related to high frequency rerendering in react? If it's the case take a look at animated (https://github.com/animatedjs/animated). You can use it to update dom styles out of the react render loop.
