copied!<h2>Dynamic requests</h2> <p>node.js is very good at handling at lot small dynamic requests(which can be hanging/long-polling). But it is not good at handling large buffers. Ryan Dahl(Author node.js) explained this one of <a href="http://nodejs.org/jsconf2010.pdf">his presentations</a>. I recommend you to study these slides. I also watched this online somewhere.</p> <h2>Garbage Collector</h2> <p>As you can see from slide(13 from 45) it is bad at big buffers.</p> <p><strong>Slide 15 from 45:</strong></p> <blockquote> <p>V8 has a generational garbage collector. Moves objects around randomly. Node can’t get a pointer to raw string data to write to socket.</p> </blockquote> <h2>Use Buffer</h2> <p><strong>Slide 16 from 45</strong></p> <blockquote> <p>Using Node’s new Buffer object, the results change.</p> </blockquote> <p>Still not that good as for example nginx, but a lot better. Also these slides are pretty old so probably Ryan has even improved this.</p> <h2>CDN</h2> <p>Still I don't think you should be using node.js to host static files. You are probably better of hosting them on a CDN which is optimized for hosting static files. <a href="http://en.wikipedia.org/wiki/Content_delivery_network#Content_delivery_service_providers">Some popular CDN</a>'s(some even free for) via WIKI.</p> <h2>NGinx(+Memcached)</h2> <p>If you don't want to use CDN to host your static files I recommend you to use <a href="http://www.igvita.com/2008/02/11/nginx-and-memcached-a-400-boost/">Nginx with memcached</a> instead which is very fast.</p>
