           Summary: REGRESSION [r78794-r79249] Allocation of memory is
                    slow when number of active objects is large
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: Tam at SiuLung.com


1. Open the attached html using webkit r78249 or later.

Try the same for:
* Safari 5.0
* WebKit trunk r78794 or before
* Any version of Chrome

Notice how it is 10x slower than all others, where a pass (after the first dozen passes) takes >1000ms, rather than <100ms as other browsers do.
