           Summary: Extremely poor performance when selecting in large table
           Product: WebKit
           Version: 522+ (nightly)
          Platform: PC
               URL: http://bugs.webkit.org/attachment.cgi?id=3234&action=vie
                    w
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: allen.sam at gmail.com


Attachment 3234, which I posted 2 years ago, has always shown poor performance
when selecting text near the top of the table. On my old Mac mini, the
performance noticably lagged behind the other browsers, even though loading the
page was fast. 

The behavior I am seeing on Windows Vista Safari 3.0.3 and WebKit ToT is much
worse. 

When I open the attachment from my hard disk and make a selection across the
cells near the top, Safari hangs and is unresponsive for 2 minutes. 

So, Safari takes 2 minutes to do what every other browser I tested can do in
less than 1 second. I don't know if this is a regression per se because I
haven't tested a recent build on the Mac.
