title: Selenium.WebDriver.ChromeDriver slow to launch - why?
body: <p>I've created the simplest-possible NUnit test to initialise a <code>ChromeDriver</code>, and it's taking nearly 6 seconds to run.  Most of the time (roughly 4s) is spent with a blank, inactive Chrome window.</p>

  <p>The ChromeDriver.exe window appears almost instantly.</p>

  <p>My unit test looks like this:</p>
  
  <pre><code>[Test]
  public void Simplest_Possible_Test()
  {
      var options = new ChromeOptions { Proxy = null };
      using (new ChromeDriver(options))
      {
          // Do nothing
      }
  }
  </code></pre>
  
  <p>and I'm using these nuget packages:</p>
  
  <pre><code>  &lt;package id="NUnit" version="3.12.0" targetFramework="net47" /&gt;
    &lt;package id="Selenium.Support" version="3.141.0" targetFramework="net47" /&gt;
    &lt;package id="Selenium.WebDriver" version="3.141.0" targetFramework="net47" /&gt;
    &lt;package id="Selenium.WebDriver.ChromeDriver" version="78.0.3904.7000" targetFramework="net47" /&gt;
  </code></pre>
  
  <p>My question is:</p>
  
  <p><strong>Is this slowness expected?  Can I do anything to speed it up?</strong></p>
