Hi, we at ULPGC are using moodle 4.5.10 and 4.5.11 on sites with 20000 users and 3000 courses. We have all courses synced to Teams: setting local_o365 | coursesync set to all features enabled.
We are experiencing a significant performance degradation in moodle due to connection to azure/o365.
Updating an existing activity can take up to 2-3 min. Even simply making an activity or section hidden/visible takes minutes, not seconds. The delay depends on the number or enroled users in the course. There is no penalty in test courses with a couple of students.
We have traced the problem to the observers in local/o365/classes/feature/calsync/observers.php for
calendar_event_created
calendar_event_updated
calendar_event_deleted
If we disable (return true immediately upon calling) those methods, there is no delay in moodle operations. When active, the update of a course_module is delayed because events syncing with outlook calendar. The delay can be of several minutes, unusable.
These is a setting in Microsoft block plugin (also installed) to control syncing with Outlook calendar; block_microsoft | settings_showoutlooksync. But these observers belong to local_o365 and do not follow that setting
We miss a setting in local_o365 to disable or configure the event synchronization with Outlook calendar directly there, in local_o365.
Technically, the observer action is quite time consuming, thus a problem if executed synchronously. Better to create and store an adhoc task than can be executed separately in backend, avoiding delays in response to user interface.
