            Bug ID: 235536
           Summary: Remove VM::stringCache
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: heycam at apple.com

We consult VM::stringCache when creating a JSString, but since bug 142115 we never insert anything into it.

Removing this results in almost-significant improvements in the VueJS, Vanilla-ES2015, and jQuery sub-tests of Speedometer 2 (of 0.5-2%, 0.03 <= p <= 0.05), and an almost significant 0.2% improvement in the overall score (p = 0.06).
