Phat

An asynchronous sample Rails app designed to run in thin.

Phat comes pre-configured to use Fiber-enabled asynchronous libraries for maximum scalability: em_postgresql, memcache-client and em-resolv-replace.

Usage

You must be running Ruby 1.9.x.

You'll need to initialize the application's gem bundle:

gem install bundler
bundler install --relock

Now just start the server:

thin -D start

Caveats

The Rails database rake tasks do not use EventMachine. Because of this, em_postgresql will fall back to blocking behavior if EM is not running.

The Rails 2.3.5 database rake tasks hard code the supported list of adapters such that "em_postgresql" is not supported. You will need to edit rails-2.3.5/lib/tasks/databases.rake and change all instances like so:

• when "postgresql"
  

• when /postgresql/
