FR Dictionaries

Hi all.. inside of /usr/local/etc/raddb/dictionary we found the line : $INCLUDE /usr/local/share/freeradius/dictionary inside of /usr/local/share/freeradius/dictionary.. there are many $INCLUDE that call all dictionary.xxx Seems that we are not using all the hardware platform listed at /usr/local/share/freeradius, can we put hash / # in front of the $INCLUDE that we not used ? such as 3COM, Cisco, etc ? I believe there will be more memory used if we call all of the dictionaries compare to the necessaries only. TIA PD
