           Summary: REGRESSION: 1% JavaScript performance regression fro
                    Window refactoring
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P1
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mjs at apple.com


Recent refactoring for the Window object's JS bindings has caused a 1% speed
regression in JavaScript iBench and the "Celtic Kane" JavaScript speed test
<http://celtickane.com/projects/jsspeed.php>. It shows up as 3% on the math
test of that benchmark specifically. Inlining Window::impl() and
DOMWindow::frame() fixes the regression.
