the time to refresh and load pages GRC PC 10

Hi Experts,

I have a problem in GRC PC 10: the time to refresh and load pages when a specific user clicks on the different work center is very slow.

It's not a authorization problem: with sap_all profile the user has the same problem.

With a new user, created to copy specific user, the problem does not occur.

I have traced specific user (ST01) and I have seen that there is a query of table HRP1000 with otype=OF à4550 records.

With other user the query of TABLE HRP1000 is carried with otype=O8 à3 records.

Kindly provide your suggestions on this.

Thanks in advance !!
