    interface PerformanceTimelineOptions {
        keep?: boolean;
        track?: string;
        trackGroup?: string;
    }
    Index
    keep? track? trackGroup?
    keep?: boolean

    Keep the entries in the performance timeline (default false). DevTools recordings and PerformanceObservers see every entry either way; keeping them makes performance.getEntriesByType('measure') return them but grows memory in long-running pages.

    track?: string

    DevTools track name (default "traceperf")

    trackGroup?: string

    Optional DevTools track group
