https://community.dynatrace.com/t5/Open-Q-A/Why-is-SuspensionTime-longer-than-ResponseTime/m-p/268305#M35498 <P>Hi</P> <P>We are investigating performance issues with <A href="https://aras.com/" target="_self">Aras Innovator</A> using Dynatrace.<BR />We found that GC Suspension was occurring when response times worsened.<BR />However, as we continued our investigation, we found a strange situation in the distributed trace. SuspensionTime was shown to be longer than ResponseTime. I thought that SuspensionTime was included in ResponseTime and that SuspensionTime would be shorter than ResponseTime.</P> <P>Does anyone know what situation would cause SuspensionTime to be longer than ResponseTime?</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Shirai_0-1737711775252.png" style="width: 400px;"><img src="https://community.dynatrace.com/t5/image/serverpage/image-id/25938i5196FDE79CBADD5B/image-size/medium?v=v2&amp;px=400" role="button" title="Shirai_0-1737711775252.png" alt="Shirai_0-1737711775252.png" /></span></P> <P>Regard.<BR />Toshimasa Shirai.</P> Mon, 27 Jan 2025 07:00:15 GMT Shirai 2025-01-27T07:00:15Z https://community.dynatrace.com/t5/Open-Q-A/Why-is-SuspensionTime-longer-than-ResponseTime/m-p/268305#M35498 <P>Hi</P> <P>We are investigating performance issues with <A href="https://aras.com/" target="_self">Aras Innovator</A> using Dynatrace.<BR />We found that GC Suspension was occurring when response times worsened.<BR />However, as we continued our investigation, we found a strange situation in the distributed trace.

It is usually caused by garbage collection.".</P><P>When you look into times of your requests, you can see that bottom 4 ran at almost same time, so probably Suspension time was calculated for all those requests that fell into same time bucket. Not sure how many requests are above upper one request.</P> Mon, 03 Feb 2025 11:58:14 GMT https://community.dynatrace.com/t5/Open-Q-A/Why-is-SuspensionTime-longer-than-ResponseTime/m-p/269058#M35595 rastislav_danis 2025-02-03T11:58:14Z
