Hi all,
After following the upgrade process to upgrade from 6.0.x through to 6.5.5, we noticed that the agent dashboard was taking a very long time to display. Users also started receiving timeouts on other actions.
We found out that some queries on the database were taking an incredibly long time (3-5 mins), degrading database performance to the point where Znuny became unusable until we killed those problematic queries.
The query in question:It is performed by a new dashboard widget introduced in Znuny 6.4.4, https://github.com/znuny/Znuny/pull/177
My questions:

The query in question:
Code:
SELECT ticket_id, MAX(change_time) max_t FROM ticket_history WHERE change_by = 'xxxx' GROUP BY ticket_id ORDER BY max_t desc LIMIT 10;My questions:
- Is there some kind of optimization I can run on the table in question (ticket_history) to speed up this query?
- Is there a way to permanently disable some widgets? For now I've set the default for the dashboard to 0 but I'd like to remove it completely
- Should I file a bug report for this?
