I'm not sure about performance vs wrk (don't kwow wrk), but just to give an idea: I noticed you're not using Tokio Hyper. Try Hyper's master branch, which fully embraces Tokio's async. EDIT: From wrk's README: > wrk is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It combines a multithreaded design with scalable event notification systems such as epoll and kqueue. Your example is multithreaded but IIRC release Hyper isn't using event notification async, which Tokio Hyper does. It might help.
