title: How to calculate bandwidth usage for Javascript?
body: <p>I want to calculate how much bandwidth a some Javascript code will consume, based on what I'm seeing in Chrome's developer tools.</p>
  
  <p>The script is initiated through a one-liner Javascript tag, referencing the external JS file.</p>
  
  <p>In the looking at the Initiator and Size Columns:</p>
  
  <pre><code>Initiator                    Size
  -------------------------------------------
  Default.aspx                 4.39kb
  Parser                       10.54kb
  </code></pre>
  
  <p>That Javascript file exists on my server, so I want to calculate how much bandwidth each call will consume from my server connection (not where Default.aspx resides).</p>
  
  <p>So my server serves up the .JS at 4.39kb - or is that the bandwidth consumption for the request, and the response is 10.54kb?</p>
  
  <p>What does the parser portion refer to, and is it safe to say that the total bandwidth usage to serve up a response for this request 15.47kb from my server?</p>
  
  <p>Thanks.</p>
