It's not 100x as stated by the OP, but I wouldn't use it (async_hooks) in situations where performance is actually a concern. I wouldn't use node there either, but that's besides the point.
async_hooks are 100% usable in production right now, we use it at my current gig for tracing and its had minimal impact on the services using it.
