Category: payload.data.vm.perfNav
`navigationStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the prompt to unload terminates on the previous document in the same browsing context. If there is no previous document, this value is the same as `PerformanceTiming.fetchStart`.
`unloadEventStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the unload event has been thrown. This indicates the time at which the previous document in the window began to unload. If there is no previous document, or if the previous document or one of the needed redirects is not of the same origin, the value returned is `0`.
`unloadEventEnd`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the unload event handler finishes. If there is no previous document, or if the previous document, or one of the needed redirects, is not of the same origin, the value returned is `0`.
`redirectStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the first HTTP redirect starts. If there is no redirect, or if one of the redirects is not of the same origin, the value returned is `0`.
`redirectEnd`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the last HTTP redirect is completed. This is when the last byte of the HTTP response has been received. If there is no redirect, or if one of the redirects is not of the same origin, the value returned is `0`.
`fetchStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the browser is ready to fetch the document using an HTTP request. This moment is before the check to any application cache.
`domainLookupStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the domain lookup starts. If a persistent connection is used, or the information is stored in a cache or a local resource, the value will be the same as `PerformanceTiming.fetchStart`.
`domainLookupEnd`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the domain lookup is finished. If a persistent connection is used, or the information is stored in a cache or a local resource, the value will be the same as `PerformanceTiming.fetchStart`.
`connectStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the request to open a connection is sent to the network. If the transport layer reports an error, and the connection establishment is started again, the last connection establishment start time is given. If a persistent connection is used, the value is the same as `PerformanceTiming.fetchStart`.
`connectEnd`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the connection is opened network. If the transport layer reports an error, and the connection establishment is started again, the last connection establishment end time is given. If a persistent connection is used, the value is the same as `PerformanceTiming.fetchStart`. A connection is considered as opened when all secure connection handshake or SOCKS authentication is terminated.
`secureConnectionStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the secure connection handshake starts. If no such connection is requested, it returns `0`.
`requestStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the browser sent the request to obtain the document from the server or from a cache. If the transport layer fails after the start of the request, and the connection is reopened, this property is set to the time corresponding to the new request.
`responseStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the browser received the first byte of the response from the server, from a cache, or from a local resource.
`responseEnd`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the browser received the last byte of the response or that the connection is closed (if this happens first) from the server, from the cache, or from a local resource.
`domLoading`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the parser started its work. That is when its `Document.readyState` changes to loading, and the corresponding readystate change event is thrown.
`domInteractive`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the parser finished its work on the main document. That is when its `Document.readyState` changes to interactive, and the corresponding readystate change event is thrown.
`domContentLoadedEventStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that is just before the parser sent the `DOMContentLoaded` event. That is just after all the scripts that must be executed immediately after parsing has been executed.
`domContentLoadedEventEnd`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, just after all the scripts that must be executed as soon as possible (in order or not) have been executed.
`domComplete`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the parser finished its work on the main document. That is when its `Document.readyState` changes to complete, and the corresponding readystate change event is thrown.
`loadEventStart`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the load event was sent for the current document. If this event has not yet been sent, it returns `0`.
`loadEventEnd`	`window.performance.timing`	An unsigned long long that represents the duration in milliseconds, since the UNIX epoch, that the load event handler terminated. That is when the load event is completed. If this event has not yet been sent or is not yet completed, it returns `0`.
