window.performance.timing -- defined in the W3C NavigationTiming specification, only exposes performance metrics of the root document's page load.

window.performance。计时——在W3C NavigationTiming规范中定义，只公开根文档页面负载的性能指标。

The W3C ResourceTiming specification, on the other hand, exposes performance information for all of the page's resources, such as img, script and XMLHttpRequest. ResourceTiming is implemented in IE10+ and is currently prefixed in Chrome.

另一方面，W3C ResourceTiming规范公开了页面上所有资源的性能信息，如img、脚本和XMLHttpRequest。ResourceTiming在IE10+中已经实现，目前在Chrome中已经有了前缀。

If you need the same level of information that you get using window.performance I think that the answer is NOT.

如果您需要与使用窗口相同的信息级别。我认为答案是否定的。

In the w3.org spec of XMLHttpRequest you only find a list of events, using that you could get some times, but not the same detail of network times.

在XMLHttpRequest的w3.org规范中，您只能找到一个事件列表，使用它您可以获得一些时间，但不能获得相同的网络时间细节。

Maybe you can look for something similar to Firebug-NetPanel, which is using a XPCOMInterface nsIHttpActivityObserver

也许您可以查找类似于Firebug-NetPanel的内容，它使用的是XPCOMInterface nsIHttpActivityObserver
