Hi,
After upgrading to 3.1.3, I noticed that Feng Office is very very slow and almost unusable for us (we have about 12.000 tasks).
When watching at MySQL log, to display tasks in a specific workspace (whci contains many other workspaces and a lot of tasks), here is the number of requests I have:
1.7.5 : 750 queries (mostly of the type Query SELECT * FROM `og_workspace_objects` WHERE `object_manager` = 'ProjectTasks' AND `object_id` = 8600)
3.1.3 : 5400 queries (mostly complex requests whith joins)
You will find logs in attachment.
Regards,
Fred
