Check for:

rulesEngine.cache.timeout

The number of seconds before an entry in the cache expires. Increasing the length of the cache timeout if content doesn't change rapidly (what is the case for this customer), the default value is 300.

rulesEngine.cache.timeout=36000

rulesEngine.cache.enabled.collectionName and rulesEngine.cache.timeout.collectionName

rulesEngine.cache.enabled.collectionName = The variable collectionName is the fully qualified path to the resource collection in Personalization.
rulesEngine.cache.timeout.collectionName = The same as rulesEngine.cache.timeout, except that this property applies to a specific resource collection.

rulesEngine.cache.enabled.ibmpznnt:rule=true 
rulesEngine.cache.timeout.ibmpznnt:rule=36000

rulesEngine.cache.enabled.ibmpznnt:campaign=true
rulesEngine.cache.timeout.ibmpznnt:campaign=36000

rulesEngine.cache.enabled.ibmpznnt:ruleMappings=true 
rulesEngine.cache.timeout.ibmpznnt:ruleMappings=36000

rulesEngine.cache.enabled.ibmpznnt:resourceCollection=true
rulesEngine.cache.timeout.ibmpznnt:resourceCollection=36000

rulesEngine.cache.enabled.ibmpznnt:applicationObject=true
rulesEngine.cache.timeout.ibmpznnt:applicationObject=36000

rulesEngine.cache.enabled.ibmpznnt:uuidPathConversion=true
rulesEngine.cache.timeout.ibmpznnt:uuidPathConversion=36000

rulesEngine.cache.enabled.ibmpznnt:jcrNodeType=true  
rulesEngine.cache.timeout.ibmpznnt:jcrNodeType=36000

rulesEngine.attributeBasedAdmin.enableCaching

Use this property to determine whether or not to cache the results of rules used in attribute based admin.

rulesEngine.attributeBasedAdmin.enableCaching=true

rulesEngine.user.nestedGroupLookup

In addition, there is an undocumented property which can be set to false to speed up PZN. This should only be done if (and only if) nested groups are NOT used in the authorization ACL lists in Portal

rulesEngine.user.nestedGroupLookup=false

rulesEngine.bypassWebContentLink

By default PZN returns results for content links as well as items, it is recommend disables support for links, queries will run about twice as fast. Set in PersonalizationService.properties

rulesEngine.bypassWebContentLink=true
