   [  Memory issues  ]

   NGX lets you take advantage of the fact that most NG databases do not
   use the memory 'allowed'. Only few database files have menus larger than
   1 kb (max. is approx. 5 kb). Statistics show that 93% of the 'long' en-
   tries are less than 2 kb in size; 99.6% are less than 13 kb (max. is 17
   kb). Similarly, most list structures are less than 13 kb.

   Unless you have nothing better to do with your RAM, it makes good sense
   to experiment with the .ini file to bring down memory consumption, and
   it is safe to do so: NGX will read as many menus as the menu buffer can
   hold, and you'll get a message if a list or long entry is larger than
   the entry buffer.

   Below is NGX's
