Problem with rlm_realm

Hi, I M using freeradius-server 2.1.7. The authentication rate i m getting is just 4 or 5. when i put a timestamp in each of the modules, i found out that the module "rlm_realm" is called about 12 times in each authentication. That is in each handshake between the mobile unit and the radius server the rlm_realm is called many a times. how can i minimize this so that it is called only once. bcoz i m not using any realms.
