connectEnd → double: The connectEnd read-only property returns the DOMHighResTimeStamp immediately after the browser finishes establishing the connection to the server to retrieve the resource. The timestamp value includes the time interval to establish the transport connection, as well as other time intervals such as TLS handshake and SOCKS authentication.

no setter
serverTiming → JSArray<PerformanceServerTiming>: The serverTiming read-only property returns an array of PerformanceServerTiming entries containing server timing metrics.
no setter
startTime → double: The read-only startTime property returns the first recorded for this . The meaning of this property depends on the value of this entry's PerformanceEntry.entryType.
no setterinherited
transferSize → int: The transferSize read-only property represents the size (in octets) of the fetched resource. The size includes the response header fields plus the response payload body (as defined by RFC7230).
no setter
workerStart → double: The workerStart read-only property of the PerformanceResourceTiming interface returns a DOMHighResTimeStamp immediately before dispatching the FetchEvent if a Service Worker thread is already running, or immediately before starting the Service Worker thread if it is not already running. If the resource is not intercepted by a Service Worker the property will always return 0.
no setter
