Fastest way to grant cube permissions per AMO (250 roles, 30 cubes)?

Question

Hi there,
can anybody tell me the fastest way to grant cube permissions in a scenario, where for example 250 roles have to be granted for 30 cubes?
Now, I do it with AMO, iterating throgh the roles, setting cube permissions.
My method for granting access looks like this:
public void GrantCubePermission(Role pRole, Database pDatabase, string pCubeName, ReadAccess pReadAccess, WriteAccess pWriteAccess, ReadSourceDataAccess pReadSourceDataAccess, bool pProcess, ReadDefinitionAccess pReadDefinitionAccess)
try
if (pRole == null) return;
Cube cube = pDatabase.Cubes.FindByName(pCubeName);
if (cube == null) return;
CubePermission cubePermission = cube.CubePermissions.FindByRole(pRole.ID);
if (cubePermission == null)
cubePermission = cube.CubePermissions.Add(pRole.ID);
cubePermission.Read = pReadAccess;
cubePermission.Write = pWriteAccess;
cubePermission.ReadSourceData = pReadSourceDataAccess;
cubePermission.Process = pProcess;
cubePermission.ReadDefinition = pReadDefinitionAccess;
cubePermission.Update(UpdateOptions.AlterDependents, UpdateMode.UpdateOrCreate);
catch (Exception ex)
Msg(ex.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
Doing it this way, the operation tooks about 4 seconds per role (the given method is executed 30 times per role, the number of the cubes to be granted for).
Finally, for 250 roles, the operation tooks about 16 minutes.
Is there a way to do it faster?
