Rack::Profile

Assists in profiling your rack application.

Installation

# install
$ gem source add http://gems.github.com
$ gem install ddollar-rack-profile

# add a use line to your builder
require 'rack/debug'
Rack::Builder.new do
  use Rack::Profile, :html => '/tmp/profile.html'
  run MyApp.new
end

# can specify any of three output types
use Rack::Profile, :html => 'profile.html', :text => 'profile.txt', :tree => 'profile.prof'

Notes

Each request will overwrite any previous request’s profile output. This is sufficient for my current needs, but I welcome patches to deal with this more gracefully.
