Using a server like Mongrel will be much faster than using a full-featured Rails
server, and you??™ll be able to serve more clients in the given amount of memory.
Of course, Rails takes up memory for a reason: it does numerous great things for you
automatically. So if you need features such as sessions or complex templating, you??™re
probably better off creating a Rails application.
Nonetheless, for conceptually simple and lightweight purposes, writing a small Mongrel
web server is a great way to make your application have less code, take less memory,
and run faster.
