Nice article FZambia. I learned a lot in details about Websockets. It totally makes sense to write any i/o bound servers in golang.
Thanks for feedback, I thought the article left fully unnoticed here:) Go also has a small disadvantage for writing WebSocket apps – you don't have full control on read buffer reuse (since its got allocated for entire lifetime of connection) thus memory consumption per connection is more than it could be. Otherwise I am pretty happy with Go for this task.
