Sorry my english.
First you have to consider an application runs over a system user. The only user who can open ports below 1024 is root. Apache, Nginx, etc. solved this, running a master process as root, and created forks that run on non-root users.
Nginx runs as root and do not do any forks. It just downgrades permissions after it starts. Node.js can do the same:
Run any interpreter (VM) under root is a big risk not worth being taken.
Running everything under root is a risk. VMs are no different.
That is on one hand, on the other, web servers like Apache or Nginx has many resolved things that should be implemented on node.js from zero.
I've been using nginx as reversal proxy for node.js applications, and I can say that the performance is not affected, especially if instead of using network ports used unix sockets.
I think if it makes the whole process of verification and analysis that makes nginx on buffer sizes, head supports, etc.. in node.js, you lose more performance than a software built directly in C for this purpose.
--2013/10/15 Norman Paniagua <[email protected]>What? nodejs vs webservers? yes, my real question is, there is lost performance if you put your multiple nodejs apps behind a webserver (with proxy)?Or its just better to use the node itself to run all your apps (using vhost if all the apps are using express)? or have a nodejs router like multi-sites?The idea behind this is just to know what way its better, some cons of using webserver like apache (don't know if its applicable to nginx) its thatwebsockets didn't work.Regards--
