title: Selenium slow to start driver
body: <p>Take the following code:</p>
  
  <pre><code>from selenium import webdriver
  browser = webdriver.Chrome()
  browser.quit()
  </code></pre>
  
  <p>This code takes around 5 seconds to run. As I understand it, ChromeDriver is starting a new instance of Chrome each time this is run.</p>
  
  <p>This is running on Ubuntu 12.04.</p>
  
  <p>In my application speed is of high importance. Is there a way to make this run quicker?</p>
  
  <p>Thanks</p>
