title: Chrome slower when console open at page load
body: <p><code>1 Load page with webgl</code> --fast.</p>
  
  <p><code>2 Open console</code> --slower, 60fps but spikes of much lower</p>
  
  <p><code>3 Refresh with console open</code> -- Page starts to drop to a crawl, like not many fps.</p>
  
  <p><code>4 close and reopen console log</code> -- Page responds similar to #2</p>
  
  <p>What is causing me to need to re-open console.log -- syntax highlighting or async debugging?</p>
