It achieves a lower byte hit rate than LFUDA though, since it evicts larger (possibly popular) objects. <p> <b> Heap LFUDA: Least Frequently Used with Dynamic Aging </b> - The Heap LFUDA policy keeps popular objects in cache regardless of their size and thus optimizes byte hit rate at the expense of hit rate since one large, popular object will prevent many smaller, slightly less popular objects from being cached. <p> <b> Heap LRU: Last Recently Used </b> - Works like LRU, but uses a heap instead. <p> Note: If using the LFUDA replacement policy, the value of Maximum Object Size should be increased above its default of 12KB to maximuze the potential byte hit rate improvement of LFUDA.</description> + <default_value>heap GDSF</default_value> + <type>select</type> + <options> + <option><name>LRU</name><value>lru</value></option> + <option><name>Heap LFUDA</name><value>heap LFUDA</value></option> + <option><name>Heap GDSF</name><value>heap GDSF</value></option> + <option><name>Heap LRU</name><value>heap LRU</value></option> + </options> + </field> + <field> + <fielddescr>Cache replacement policy</fielddescr> + <fieldname>cache_replacement</fieldname> + <description>The cache replacement policy decides which objects will remain in cache and which objects are replaced to create space for the new objects.
