Choosing a web server

Doing some work with HTML5 WebSockets ATM and been looking at the different web servers, found this great post on the web and thought I would share.

Choosing the right one

The choice is mainly made by the server and middleware you use:

• Multi-Process, non-preforking: Mongrel, Thin, WEBrick, Zbatery
• Multi-Process, preforking: Unicorn, Rainbows, Passenger
• Evented (suited for sinatra-synchrony): Thin, Rainbows, Zbatery
• Threaded: Net::HTTP::Server, Threaded Mongrel, Puma, Rainbows, Zbatery, Thin[1]

[1] since Sinatra 1.3.0, Thin will be started in threaded mode, if it is started by Sinatra (i.e. with ruby app.rb, but not with the thin command, nor with rackup).
