[David Horwitz]

You might want to look at this fix too:

https://jira.sakaiproject.org/browse/SAK-23524 (Roster)

its a similar pattern to the GB one bellow and caused us some pain.

I haven't observed any issues that would explain gigantic memory usage CPU spiked at 100%.  I would try to get a heap dump into Eclipse MAT as soon as possible.

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?
