If you have a lot of objects, then the response time of JOC slowed down.
This is especially reflected in the list view of the objects.
The tree view can be much faster.
The tree view is implemented since release 1.3.8 for jobs and job chain and since 1.3.12 also for orders and schedules.
While in the list view all objects of the current tab will be displayed, in the tree view only the objects of opened folders are displayed.
So, the Job Scheduler answer after an update of a list view contains all objects of the current tab, making the answer correspondingly large.
If you have a lot of objects, then use the tree view.
This is particularly performant, if you save your objects in subdirectories of the Hot Folder (./config/live).
In this case are not all objects of the current tab in the JobScheduler answer, but only those of the opened directories.
Further the performance depends on the network velocity.
You can check the response time if you switch on the log window. For this go to Help|Extras->Settings and edit the debug leveh1. 3.
Then you see in a new tab some log lines like
[debug3]START SCHEDULER REQUEST: <commands><subsystem.show what="statistics"/><show_state .../></commands> [debug3]ELAPSED TIME FOR SCHEDULER REQUEST: 0.021s
If you want a logging of a single operation in JOC then close the log tab before you execute the operation in JOC and a clear new tab will be created.
Set the debug level0 to switch off the logging and close the log tab.
