I guess the reason is that the runtime of node is so much larger than that of Python and PHP. I think the Node runtime is already at > 50MB as a binary.

I don't know how large Python and PHP runtimes are, but I know python is often stripped down to a few kilobytes for embedded systems.

I guess if you preload the runtimes before executing these commands, the execution should be fairly similar for each one (near zero, more depending on I/O).
