title: Selenium using too much memory
body: <p>I'm using selenium on python 3.5 with chrome webdriver on a ububtu vps, and when I run a very basic script (navigate to site, enter login fields, click), memory usage goes up by ~400mb,and cpu usage goes up to 100%. Are there any things I can do to lower this, or if not, are there any alternatives?</p>
  
  <p>I'm testing out selenium in python but I plan to do a project with it in java, where memory usage is a critical factor for me, so the same question applies for java as well.</p>
