  <p>Hi, thanks for coming to my session at CodeMash 2012. Here are the slides:</p>

<p><a href="http://speakerdeck.com/u/j3/p/metrics-driven-rails-performance">http://speakerdeck.com/u/j3/p/metrics-driven-rails-performance</a></p>

<p>The sample project I used is available here:</p>

<p><a href="https://github.com/jumpstartlab/jsblogger_advanced">https://github.com/jumpstartlab/jsblogger_advanced</a></p>

<p>To get it ready to rock:</p>

<ul>
<li>Run <code>bundle</code></li>
<li>Open the <code>db/seeds.rb</code> and change the <code>10.times</code> to <code>1000.times</code></li>
<li>You may optionally want to implement pagination on the <code>Articles#index</code> page. I used Kaminari following this tutorial: <a href="http://tutorials.jumpstartlab.com/topics/better_views/pagination.html">http://tutorials.jumpstartlab.com/topics/better_views/pagination.html</a></li>
<li>Follow the directions in the slides</li>
</ul>

<p>Enjoy!</p>

<p>It&#8217;s a great jumping-off point if you want to dive into the depths of deep debugging/performance.</p>
