In the "hello world" web server example above, many - client connections can be handled concurrently. Node tells the - operating system (through <code>epoll</code>, <code>kqueue</code>, - <code class="sh_none">/dev/poll</code>, or <code>select</code>) - that it should be notified when a new connection is made, and - then it goes to sleep. If someone new connects, then it executes - the callback. Each connection is only a small heap allocation. - </p> - - <p> - This is in contrast to today's more common concurrency model where - OS threads are employed. Thread-based networking is relatively - inefficient and very difficult to use. See: - <a href="http://www.kegel.com/c10k.html">this</a> and - <a href="http://bulk.fefe.de/scalable-networking.pdf">this.</a> - - Node will show much better memory efficiency under high-loads - <!-- TODO benchmark --> - than systems which allocate 2mb thread stacks for each connection. - - Furthermore, users of Node are free from worries of dead-locking - the process—there are no locks. Almost no function in Node - directly performs I/O, so the process never blocks. Because - nothing blocks, less-than-expert programmers are able to develop - fast systems. - </p> - - <p> - Node is similar in design to and influenced by systems like Ruby's <a - href="http://rubyeventmachine.com/">Event Machine</a> or Python's <a - href="http://twistedmatrix.com/">Twisted</a>. Node takes the event - model a bit further—it presents the event loop as a language - construct instead of as a library. In other systems there is always - a blocking call to start the event-loop. Typically one defines - behavior through callbacks at the beginning of a script and at the - end starts a server through a blocking call like - <code>EventMachine::run()</code>. In Node there is no such - start-the-event-loop call. Node simply enters the event loop after - executing the input script. Node exits the event loop when there are - no more callbacks to perform. This behavior is like browser - javascript—the event loop is hidden from the user. - </p> - - <p> - HTTP is a first class protocol in Node. Node's HTTP library has - grown out of the author's experiences developing and working with - web servers. For example, streaming data through most web frameworks - is impossible. Node attempts to correct these problems in its HTTP - <a href="https://github.com/joyent/http-parser/tree/master">parser</a> - and API. Coupled with Node's purely evented infrastructure, it makes - a good foundation for web libraries or frameworks. - </p> - - <p> - <i> - But what about multiple-processor concurrency?
