            Bug ID: 254448
           Summary: [macOS] ~1% warm PLT regression from suspending
                    webcontent process
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Mac (Apple Silicon)
                OS: macOS 13
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Process Model
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: miguel_salinas at apple.com

After enabling background WebContent process suspension we're measuring up to 1% regression in PLT-warm runs. I think this is due to calling prepareToSuspend on the WebContent process.
