run-webkit-tests takes 20 minutes longer on a Debug build than on a Release build on Windows. Here's an example of two test runs for the same revision on identical hardware:

Debug: http://build.webkit.org/builders/Windows%20Debug%20%28Tests%29/builds/21592
Release: http://build.webkit.org/builders/Windows%20Release%20%28Tests%29/builds/5601

You can see that run-webkit-tests took nearly 20 minutes longer in the Debug build. This is making our Debug test bots fall way behind.
