It may be written in JavaScript and thus has the overhead of a language VM. This especially hurts in terms of memory overhead per process. But node wins over apache and nginx by having the right event model. Good low-level primitives in libuv and the ability to script-in assumptions. For example, in the wheat engine that powers howtonode.org, My database is a git repo. I know that in git requests for the same resource using the same git sha will *never* change. So I can cache that type of request aggressively in memory. (This includes the static resources, I also store those in git) Nginx and Apache are general purpose static file servers. That's can't make that kind of caching assumptions. Node serving a static file from memory is faster than nginx serving the same file from disk. Yes javascript is slower than C, but the smarter algorithm wins out over a slower language.
