The article uses two examples to demonstrate that v8 is in fact fast. However, when using python or ruby to create a web server, the server will actually run in parallel (multiple threads), therefore, the average waiting time could be less than the node.js version.
suppose, for example, we have two people connecting to the server at the same time. if it is the node.js server, one person waited for 5 seconds, the other one waited for 10 seconds, the average waiting time is (5+10) / 2 = 7.5
assume that the python server is less efficient, which takes 7 seconds to finish the job. but it runs in parallel. so both two people waited 7 seconds.
therefore, on average, the python server is in fact, faster
