title: How, in general, does Node.js handle 10,000 concurrent requests?
body: <p>I understand that Node.js uses a single-thread and an event loop to process requests only processing one at a time (which is non-blocking). But still, how does that work, lets say 10,000 concurrent requests. The event loop will process all the requests? Would not that take too long?</p>
  
  <p>I can not understand (yet) how it can be faster than a multi-threaded web server. I understand that multi-threaded web server will be more expensive in resources (memory, CPU), but would not it still be faster? I am probably wrong; please explain how this single-thread is faster in lots of requests, and what it typically does (in high level) when servicing lots of requests like 10,000.</p>
  
  <p>And also, will that single-thread scale well with that large amount? Please bear in mind that I am just starting to learn Node.js.</p>
