(If you aren't Rack- based, you should be. Sinatra makes it easy, but even Rails is built on Rack these days.) But all of these are mostly performance-tuning hacks -- most don't fundamentally change what you're doing. > Is there a more accepted way to handle this?

I suppose something like mod_ruby might listen without a worker running, then instantiate your app when you get a request. But many other servers simply embed themselves into a running process -- that IS your app always running, waiting for a request. Unicorn combines both -- it loads your app, then forks it off into several workers, so you have MANY copies of your app always running, waiting for a request. Maybe I don't understand what you mean by "always on"?
