[Building Sakai] 2.9.1 Performance Issues

[Curtis Van-Osch]

Hello,
We at HEC Montréal recently upgraded to Sakai 2.9.1 (last monday). 
Everything went well, but we have been experiencing performance issues 
ever since.  Memory usage hovers between 6.5 and 8 gigabytes, and CPU 
usage often spikes to 100%

our JAVA_OPTS="-d64 -server -Xmx10g -Djava.awt.headless=true -Xms512m 
-XX:MaxPermSize=768m -XX:PermSize=256m -Duser.language=fr -Duser.region=CA"

We're planning on inspecting a heap dump tomorrow morning, and we're 
looking at applying this Gradebook patch 
<https://jira.sakaiproject.org/browse/SAK-23385> (SAK-23385).

Does anyone have any other ideas for diagnosing performance issues?
