           Summary: Cache timer heap pointer to timers
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: koivisto at iki.fi


Accessing timer heap through thread global storage is slow (~0.1% in PLT3). We can cache the heap pointer to each TimerBase. There are not huge numbers of timers around so memory is not an issue and many timers are heavily reused.
