Go as an alternative to Node.js for Very Fast Servers
I was curious, so I actually ran both of the servers from the article on my little MacBook Air. The results are below.<p>First, go:<p><pre><code>    $ ab -c 100 -n 10000 http://localhost:8000/

Not only does go serve the traffic more quickly, but it also has a much lower standard deviation between slow and long requests. Impressive.
