This is a very simple benchmark comparing the response times of a few different webservers for an extremely simple response: just reply with a snippet of static json. It came up in discussion of a real-life service: in the actual server, a long-running thread/process periodically updates the state from a database, but requests will be served with the data directly from memory. It is imperative, though, that the latencies be extremely low for this service.

This comparison was partly inspired by this blog post.
