-  The CYC server uses a least-recently-used cache management strategy to keep the information most often needed from the units files in main memory for faster access. These caches can be tuned, if necessary, to support smaller memory foot-prints for the KB objects (and consequently, less garbage collection), or larger memory foot-prints (and consequently, potentially higher through-put). All cache tuning settings have to take place before the CYC-LOAD-KB call in the init/jrtl-init.lisp start-up script.

- * Each cache is controlled by two integer values:

+ All cache tuning settings have to take place before the CYC-LOAD-KB call in the init/jrtl-init.lisp start-up script.
- ** a maximum number of entities as the size cap on the cache size
+* Each cache is controlled by two integer values:
   At cache allocation time, the CYC server computes the percentage of the total as a number of entities, looks up the maximum and takes the smaller of the two values as the limit.
   The following specifies the parameters to set for the available caches and gives their 2011 default values. These default values are appropriate to a wide variety of uses of CYC.
