Well, after some research it seems Go is pretty fast for starters. The backend I'm building is expected to be accessed by more than 10k people on a daily basis so it has to be robust. One of the other features I'm really looking forward is the built-in web server it offers. Basically I heard it's strong, scalable and neat for a service that needs a lot of requests per day, so it seems like a good idea to give it a try.
