           Summary: Loading large pages spikes CPU usage tremendously
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh Intel
               URL: http://www.gnu.org/software/autoconf/manual/autoconf-
                    2.57/html_mono/autoconf.html
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: tyler at bleepsoft.com


When accessing the aforementioned autoconf manual page which is substantially
large, WebKit CPU spikes to ridiculous proportions, sometimes as high as ~85%
on my intel iMac. When returning focus to the browser from another application,
or switching to the tab in which this page resides, the CPU load spikes again
the ~15-20% and then slowly tapers off. While browsing such a large page, loads
will spike up to ~30% as well while _scrolling_ the page (it's almost
relational to how fast I scroll, but that's unscientific to say the least ;)).
