            Bug ID: 204799
           Summary: Network Load metrics are wrong when resources are
                    loaded from the memory cache
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: cdumez at apple.com

Network load metrics are populated by CFNetwork in the network process. If you navigate back to a page without using the back/forward cache, a lot of the resources will come from the memory cache and Web Inspector will report confusing values for those loads (especially "Response Download").

On nytimes.com, when navigating back from an article to the main page, Web Inspector was telling me that the resource came from the memory cache (GOOD) but took 800ms to download (WRONG).
