Performance for Custom folder in Discoverer

Question

Hi there, thanks for all your helping questions and sharing your thoughts.
I got issue from user regarding Custom folder in Discvoerer while they try to run report, becoz there are item classes i created and its taking so long time to fetch LOVs.
Below is the query, I used to create custom folder and also created 3 LOVs (item classes) in Discverer Administrator, it is working well and good.
According to the requirement ( you can see bottom of this page) this is the query, Can anyone help me on how to improve performance, in TOAD the query takes long time, so for Item classes also it takes long time. Any ideas would be greatly appreciated, thanks in advance.

Requirement================
We have made use of modifications to a Discoverer report called 'Oracle Users and Responsibilities'. We use the report to review Oracle users and their associated responsibilities. We would like to see if it would be possible to make another report with fields from the above SQL query. The intent is to note when users last made use of a responsibility (last logged on with a responsibility). The above query needs some revision in the fact that it currently only returns responsibilities a user has logged in with. Ideally, we would like to also return the responsibilities a user has not logged in with. If a date parameter is supplied for a report, the end-user will be able to return all users, their responsibilities, and the last time the users logged in. The attached query can specify a user or the user's creation date; ideally, one would also be able to only pick responsibilities user(s) had prior to a specified date. Thus, if they wished to run a report to return all the users and the last time they logged in with their responsibilities if they have had the responsibility for at least 90 days, he could readily do so.

Hi,
You could try this query, but whether it will be quicker depends on how you are using the custom folder in your reports.
