            Bug ID: 165857
           Summary: [JSC] Optimize Kraken stringify
    Classification: Unclassified
           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: utatane.tea at gmail.com

In Kraken's stringify test, roughly 30% of time is used by StringBuilder::appendQuotedJSONString.
I think we have room for optimization in this function.

I have a patch that shows 1% performance improvement in Linux box, but I need to test it with macOS clang.
