# http4k

I dont know what the right place is to have a sensible conversation about the utility of async behaviour in an http server and client code. It almost certainly isn't an "issue". Software always has some constraints - sometimes it is code size, sometimes memory size, sometimes raw performance .. but often (almost, but not actually always, IMHO, but YMMV) the limiting factor is developer productivity and ease of writing, testing and debugging.

As netflix wrote, they rewrote their zuul gateway in async, and saw a 3% uplift in performance for an unquantifiable increase in complexity.

Anyhow, for me this is great - now I see a really useful library with a strong view on its constraints, and becoming more and more useful, without a (to me) useless paradigm shift on the horizon.
