re: Write faster JavaScript VIEW POST


I have a side project in node.js which has organically grown over time to become quite large. It essentially works on a middleware pattern checking inbound messages and reacting to them. I have many middlewares that a message can pass through and I'm at the point now where I need to start optimising the order, pinpoint slow code and overall improve efficiency.

At the moment since I'm quite a noob to performance measures are there any recommendations on how I can profile the speed and overall execution areas that bog down my performance? Right now I'm reducing myself to using console.log with timestamps which obviously gets you only so far.


I highly recommend reading this article, also check out performance API
