Summary

xw's commits concentrate on WebKit's performance-testing infrastructure — the `run-benchmark` harness, browser driver configuration, and Chrome-channel flag handling (feature names for frame-throttling toggles, exposing the diagnose directory to drivers), plus triage of failing perf tests under `PerformanceTests/`. The work is entirely benchmark tooling and test plumbing rather than engine code, with no security fixes or hardening changes in the window. Nothing here touches attacker-reachable surface; the profile is test-infrastructure maintenance.
