为什么Selenium InternetExplorerDriver Webdriver在调试模式下会非常慢（Visual Studio 2010和IE9）

我正在使用SeleniumHq网站上的示例代码-但在调试模式下，性能却很糟糕。

I'm using the example code from the SeleniumHq site - but in debug mode the performance is awful.

在发布模式下，整个测试大约需要6秒钟（包括启动和关闭IE）
在调试模式下需要65秒？

In release mode the entire test takes about 6 seconds (including launching and closing IE) In Debug mode it takes 65 seconds ?

示例代码仅为：

    [Test]
    public void testBrowser()
    {
        // Do something here
        IWebDriver driver = new InternetExplorerDriver();
        //Notice navigation is slightly different than the Java version
        //This is because 'get' is a keyword in C#
        driver.Navigate().GoToUrl("http://www.google.com");
        IWebElement query = driver.FindElement(By.Name("q"));
        query.SendKeys("Cheese");
        System.Console.WriteLine("Page title is: " + driver.Title);
        // TODO add wait
        driver.Quit();

    }

我在ie8中尝试过，并且具有相同的性能。 Firefox很好-但是我的客户使用IE，所以我一直坚持对其进行测试。另外-如果使用Selenium RC，我不会遇到相同的问题。

I've tried it in ie8 and have the same performance. Firefox is fine - but my clients use IE so I'm stuck with testing against it. Also - I don't have the same issues if I use Selenium RC.

NB-我使用的是.Net 4和最新版本（2.16）的webDriver .dll（在64位Windows 7框上运行）

NB - I'm using .Net 4 and the latest version (2.16) of the webDriver.dll (running on a 64bit windows 7 box)
