Doesn't look like it. Additionally it appears to be conceptually heavy. It's hard to convince Clojure users to use anything but small libraries, even Noir (a Sinatra-like framework) was abandoned for this reason. This might be really good but the amount of buy-in required is a hard sell to the community.
Hoplon's reactive model is quite different from React's. We think it's more advanced :). There are no "performance issues" reported lately (there was some confusion with an old proof-of-concept demo, but any recent version of Hoplon will provide acceptable performance).
Hoplon isn't optimized for "perf" in rendering things on the screen. Hoplon is designed to uncompromisingly optimize developer performance. I know that when my users are presented with a choice between more rendering perf and added features in the application it's a no-brainer. They just need good performance, but great features.
Hoplon presents a model in which web designers and programmers can coexist without friction, and it provides the underlying foundation for developing truly powerful abstractions (like components, for example) that are composable in ways that are impossible in other systems.
