           Summary: SunSpider run times are not reproducible
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: pbiggar at mozilla.com


SunSpider has a very high level of variability in its run-time, especially on Linux. In Firefox, we're trying to make very small improvements to the JS VM, but we can't trust Sunspider results for any improvement of less than 15ms.

This is a meta-bug, roughly corresponding to https://bugzilla.mozilla.org/show_bug.cgi?id=580532 in the Mozilla bugzilla. I will file more specific bugs as blockers to this bug (assuming that's the way you use your bugzilla).
