Its just to share an experience i had while trying out restify framework in node.js. We had the requirement to build up a REST API in node.js and were looking for a lighter weight framework than express.js which probably avoid from the unwanted features and would act like a custom built framework for building REST APIs. Restify is recommended for the same case.
But the surprise came when i tried out both with a load.
I made a sample REST API on restify and flooded it with 1000 requests per sec. Surprise to me the route started not responding after a while. The same app built on express.js handled all.
May be i am wrong, "But do testify before you restify".
