</div>I assume this is for your development server (tycho) in the dev<br>
cluster, as your production library server is still running 2.10.1<br></blockquote><div><br></div><div>Yes, I am testing it out first before installing 2.11 on the production servers.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Were you ever able to resolve the yum update issues on your dev server<br>
caused by epel repo conflicts?<br></blockquote><div><br></div><div>Leaving the disable flag did the trick. <br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

The construction space rendering behavior you report has not been my<br>
experience on MSU single domain library servers in both the production<br>
cluster and dev cluster. When I compare rendering times for the same<br>
problem in Authoring Space on the same hardware, both before and after<br>
upgrade to 2.11.0, I find rendering times the same (about 2 s).<br>
<br>
Has the problem which you find takes ~30 s to render been published?<br></blockquote><div><br></div><div>Yes, they are the problems in openstax-CollegePhysics library. I have added you as co-author so can poke around. Just view the openstax-CollegePhysics/02_Kinematics/01_Displacement.problem - it took more than 30 s sometimes.<br>

<br>
If so, I could replicate the resource, and then measure rendering<br>
times on the MSU development server, and debug, if I also found<br>
anomalous (long) rendering times.<br>

Looking at diagnostics for tycho it appears that you still have rev<br>
1.152.2.2 of /home/httpd/html/res/adm/includes/default_homework.lcpm<br>
installed (i.e., the version included with 2.10.1) instead of rev.<br>
1.169 (the version shipped with 2.11.0). Is there a reason for that?<br></blockquote><div><br></div><div>Hum, not sure why. I run UPDATE so not sure why the old file was not replaced. I replaced it manually but do not see any improvement.<br>
