Roar[0] works great for this, we use it for our HAL APIs and I'm very happy with it.

What Hacker News says
3 sourcesJSON rendering performance is a major concern for most of my Rails apps, and I'm wondering the same thing. I've not used Roar (https://github.com/apotonick/roar) before which is what Trailblazer uses for JSON serialization/deserialization. It seems to be full-featured, but I'm interested to hear how it performs compared to other gems. I currently use OJ + Jbuilder + a ton of fragment caching and it's not great but better than anything else I could find.
In Trailblazer: A new architecture for RailsThe problem here is not just that it trashes the method cache for this object. In most versions of MRI, this trashes _all_ method caches, not just the ones for String.
A sufficiently clever JIT could find out that there is only ever a String instance extended (so, basically, the extension is monomorph) and introduce the resulting type.
However, this example is not rare. Some more:
