<div>{{APIRef("Resource Timing API")}}</div>
<p>The <strong><code>clearResourceTimings()</code></strong> method removes all {{domxref("PerformanceEntry","performance entries")}} with an {{domxref("PerformanceEntry.entryType","entryType")}} of "<code>resource</code>" from the browser's performance data buffer and sets the size of the performance data buffer to zero. To set the size of the browser's performance data buffer, use the {{domxref("Performance.setResourceTimingBufferSize()")}} method.</p>
