• There are different forms of caching within PZN - resource collection caches, visibility rule caches, and others.

However, Portal disables the PZN visbility cache by default. Modify the property in PersonalizationService.properties:

rulesEngine.attributeBasedAdmin.enableCaching=true

• 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

• 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=900

• 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
