Now our database is empty and we can't test it, sorry.
The problems the scalability detected with 40.000 users are because the table acs_permissions have 500.000 of rows.

The first of otcubre will have the 15.000 users loaded in the database and then we will make yield tests.

Galileo has:
select count(*) from acs_permissions;
(1 row)

and getting this speed:
132 ms       0or1row       dbqd.acs-tcl.tcl.acs-permissions-procs.permission::permission_p_not_cached.select_permission_p: 0or1row nsdb0

select 1 from dual
where exists
          ( select 1
                  from acs_object_party_privilege_map ppm
        where ppm.object_id = '1228' and ppm.party_id = '16319' and ppm.privilege = 'dotlrn_browse' )

As you see, the permission call has been changed lately, with 500K entries on acs_permissions you should be fine I think (though it can still be improved), specially since your db server if bigger than ours.
