[nodejs] node.js vs python tornado

[Carlos Carcamo]

what do you think about node.js vs python tornado?, which would you
choose and why?
I know this list is for node.js but I wonder if you have tried with
tornado, if this is the case, what do you think about both
technologies?

The big difference is that the entire Node.js ecosystem is built around async code. With Tornado if you use a library like an XML parser, which loads in external content via entities or xinclude, those will be loaded synchronously and block your event loop. Similarly for all kinds of other libraries in the Python ecosystem which have been designed around the assumption that everything is synchronous. I had exactly this problem when building async code in Perl, which suffers from the same assumptions.

Also the engine behind Node, V8, is significantly faster than the Python engine.

Thanks for your comments, I had doubts about to choose node.js instead tornado.
I like python syntax but for the nature of my project I will choose node.js.
