The Web Performance API allows web pages access to certain functions for measuring the performance of web pages and web applications, including the Navigation Timing API and high-resolution time data.

+ +

Methods

+ +
+
{{domxref("Performance.mark()", "performance.mark()")}}
+
Maps a {{domxref("DOMHighResTimeStamp")}} to a specified name representing the amount of milliseconds elapsed since a reference instant.
+
+ +
+
{{domxref("Performance.now()", "performance.now()")}}
+
Возвращает {{domxref("DOMHighResTimeStamp")}} представляющий количество миллисекунд прошедшее с момента отсчета.
+
measure()
+
This method stores the DOMHighResTimeStamp duration between two marks along with the associated name (a "measure").
+
getEntriesByType()
+
 
+
getEntriesByType()
+
 
+
getEntriesByName()
+
 
+
clearMarks()
+
+

If the markName argument is not specified, this method removes all marks and their associated DOMHighResTimeStamp time values.

+ +

If the markName argument is specified, this method removes all DOMHighResTimeStamp time values for the given mark name.

+ +

If the markName argument is specified but the specified markName does not exist, this method will do nothing.
+  

+
+
+ +

Properties

+ +
+
{{domxref("Performance.timing", "performance.timing")}}
+
Is a {{domxref("PerformanceTiming")}} object containing latency-related performance information.
+
{{domxref("Performance.navigation", "performance.navigation")}}
+
Is a {{domxref("PerformanceNavigation")}} object representing the type of navigation that occurs in the given browsing context, like the amount of redirections needed to fetch the resource.
+
performance.memory
+
A non-standard extension added in Chrome.
