           Summary: Bad DOM performance in large SVG files
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://paroga.com/webkit/rect.php?c=10000&s=10
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: paroga at paroga.com


When you click on the 1st rect all rects get yellow, on the 2nd they get blue.
When you click on the 3rd the first rect gets lime, on the 4th it gets red.

Setting only one rect is as slow as setting all rects.
In Firefox 3 you see a big difference between setting all or only one rect.

With the c-parameter you can change the count of the rects, with the
s-parameter the size.

Setting only one rect is much faster in http://paroga.com/webkit/rect.php?c=4
than in http://paroga.com/webkit/rect.php?c=10000.
In Firefox there is no difference.
