I find a number of the fast facts to be horribly misleading due to their brevity...<p>"Node.js runs everything in ‘parallel’, meaning that all of your tasks can be run at the same time. For example, let’s say you have a webpage that has 100 lines of code with 10 database calls. With a web server like Apache, these 10 database calls must be made in succession. While running node.js, you can run all 10 of these database calls at once, which makes the webpage load faster."<p>errr... maybe...<p>"Current web servers must open many connections to interact with their operating system (OS), while node.js only needs to open 1 connection. Each connection costs the system memory, so using fewer connections is more efficient and faster for the entire system."<p>there are many lightweight polling webservers like nginx, lighttpd etc
Fast Fact: due to a v8 bug, a Node.js process currently only supports a max of 1.9gb of RAM<p><a href="http://code.google.com/p/v8/issues/detail?id=847" rel="nofollow">http://code.google.com/p/v8/issues/detail?id=847</a>
