UMich moved to 2.6 this last Saturday, Aug 29. Our Fall term starts next
Tues Sep. 8.
We are working on a couple performance issues. Load testing revealed the
frequent query to sakai_site_page_property that others have reported. We
will be testing a fix to that this week - KNL-259. We also are changing
some of our local provider caching to reduce queries there. Our
Resources load test showed increased db utilization over 2.5 - we have
not yet figured out the cause and continue to investigate.
We have added a 'tool disabler' capability (contrib - inactivate_tools).
There is some anticipation here of markedly increased usage as a result
of high absenteeism due to flu. We have created a means of disabling any
given tool w/o a restart so as to be able to reduce load/usage quickly
in order to keep the system up, if needed.
