<h3>rgolanbb created OVIRT-1756:</h3>
<pre> Summary: configure jenkins.ovirt.org to G1 garbage collector
Key: OVIRT-1756
URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1756
Project: oVirt - virtualization made easy
Issue Type: By-EMAIL
Reporter: rgolanbb
Assignee: infra</pre>
<p>I noticed jenkins process cpu consumption going over 100% and stalling the web handlers. The io wait is not a problem nor mem.</p>
<p>What I suspect is going on is tons of GC and GC pressure given that 12GB heap and fairly nice amount of users and requests.</p>
<p>What we can do is to configure the gc logging to see if that is really GC pauses really and to move to using the G1 garbage collector.</p>
<p>See this post from cloudbees on the move to G1 collector <a href="https://www.cloudbees.com/blog/joining-big-leagues-tuning-jenkins-gc-responsiveness-and-stability">https://www.cloudbees.com/blog/joining-big-leagues-tuning-jenkins-gc-responsiveness-and-stability</a></p>
