Trying to pick a server side language
I would like to know how PHP, Python and node.js compare, when it comes to performance on the server side? Is there anyone here who's actually used all 3, and can give me a comparison?
I have Used PHP myself, and I understand how it works - it essentially lives inside your webserver. So how do the others do it? What are the RAM footprints?
I'm also (of course) concerned about what node and Python are like - are they easy to learn, and fun to program IN? :)
Thanks for all your help.
