You may want to handle the errors better before using it in production.

-
How short Go is: 80 lines.
-
How slim Go is: 3MB RAM.
-
How comprehensive Go standard library is. If
net/httpsupports basic pattern matching, this project would be 100% based on standard library. -
How quick it is to get up and running in Go. It took me about 1 hour from start to finish. Writing this README file took longer time.

How performant Go is:
