Benchmarks are performed with wrk. All of the servers tested serve the same static page, benchmark is ran 3 times and the best one of them is chosen.
FUN FACT: Microbenchmarks like this are not a good measure for "dynamic web apps" which most websites are, in that context, your bottleneck is going to be disk I/O and database queries and a metric like requests/sec doesn't measure anything meaningful. Here, there is a very specific goal -- to serve static files and the bottlenecks can be minimized and there are no external constraints hence why this benchmark exists. :)
