title: How to easily delay Query insertion in Rails 3 app
body: <p>I have one method that needs to handle large number of requests. I'm using Rack for it.</p>
  
  <p>What it does is that it receive parameters and it creates a delayed_job task:</p>
  
  <pre><code>def self.call(env)
     ...
     Delayed::Job.enqueue(....)
  </code></pre>
  
  <p>To optimize it further I thought it would be nice to make the line above happen in the Background (maybe caching it in memory to insert the Delayed job entry in DB a bit later and increase responsiveness of the Rack App).</p>
  
  <p>Any easy way to delay queuing Delayed Job task to save few milliseconds?</p>
  
  <p>Current Bench mark is 12ms / Request so even couple milliseconds will help.</p>
