title: IIS Failed Request Tracing - Performance View - doesn't show time spent
body: <p>I'm trying to troubleshoot slows requests on a website so I have configured Failed Request Tracing to trigger for requests taking 10 seconds or more. I'm getting logs but though they take 10+ seconds the performance view tab doesn't show where the time is spent. Why is that?</p>
