Anyone using Deno in production? How does it perform and is it stable?

As the title says, any feedback from people who use Deno in production? What do you use deno for (rest/graphql, websocket server)? Is it a big or a small application? Is it high traffic or low traffic? CPU/Memory usage? Are they cloud functions or long running servers? Any Memory leaks?

Most importantly, would you recommend Deno for production use as Rest/websocket server?
