Space Monkey dumps Python for Go
Well it is kind of obvious that a compiled language is going to be faster than an interpreted one, especially the way how these interpreters work (https://wiki.python.org/moin/GlobalInterpreterLock). You can fool yourself with Twisted (or in Ruby with EventMachine, Goliath etc.) but it gets so just a bit ahead. The surprising fact for me is that Go is not as much faster. I was expecting a bigger gap in the performance between Go and Python. Understanding where your bottlenecks are is crucial and it is not super hard in Go. https://www.datadoghq.com/2014/04/go-performance-tales/ I guess the SpaceMonkey guys might further improve the performance just by doing a thorough analysis on their code.
