I spent a lot of time analyzing the startup time of Java, Python, and Node.js. For any real-world program, startup time is entirely dominated by time taken to load code into memory, which in python is import statements. Also, as slow as Python 2.7 is, Node.js, at least when I measured it, was twice as slow.
