This is one of the first scripts that I made myself after migrating to ec2.  I initially programmed it in ruby, but just recently re-wrote it in Go.  I don&#x27;t cache the hosts and it usually takes around 0.5 - 0.7 seconds.  My ruby implementation was much slower due to the libraries I was using needing to be loaded in each time it ran as opposed to the Go compiling ahead of time.
