Survivor Space suddenly growing and increasing response times
<p>I have a web application deployed on a wildfly-10.1.0 application server and doing some load tests with jmeter. At a certain user count for a short amount of time response times grow rapidly and plunge to a low level again. This behavior repeats itself several times. Interesting about this is that the size of the survivor space of the wildlfy jvm is consistent with the response time (<a href="https://i.stack.imgur.com/inZxK.png" rel="nofollow">see picture</a>).</p>

<p>I already tried tuning the heap sizes of the wildfly jvm and of the young and old generation but the behavior stays the same. Has anyone an idea as to what leads the survivor space to grow in such a way and what I have to change in order to keep my response times low?</p>
