Mohamad,
On our test server it takes 64 milliseconds. You can check oxd call for RPT authorization.

It's hard to say why exactly it takes so much time on your side, it can be:
- big network latency between your client and Gluu AS. (Please try to authorize RPT directly from the same machine where Gluu AS is installed to make sure it is not network);
- no ldap indexes on your LDAP Server.
- Not enough CPU or memory for Gluu Server, check other processes on this machine.
If you configured it properly it should be quite fast.
Hope it helps,
Yuriy
