            Bug ID: 261364
           Summary: High system cpu load during IDL generation
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: emw at apple.com

On a M1 Ultra Mac Studio, WebCore’s derived sources target takes ~ 50sec to build, with most of that time spent generating IDLs. It scales to use all CPUs, but puts comparatively more load on the system than on user processes. We should figure out why this is such a system-heavy operation, and optimize it.
