           Summary: JSC GC is far too conservative about growing the heap
                    size, particularly on desktop platforms
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fpizlo at apple.com


The JSC GC tried to always bring the heap size down to 512 KB, or 2x the amount of used memory (excluding external fragmentation).  But this leads to some needless GC work, particularly since (a) the GC has some large constant-time work to do like root scanning, and (b) restricting the heap to 512 KB browser-wide is probably unnecessary.  Increasing these limits - within reason - should improve performance while having a negligible effect on overall memory usage.
