Base portal tuning (Tuning Guide 6.1.x)

Setting com.ibm.wps.ac.groupmanagement.NestedGroupCache.enabled=false (disabling this cache) can adversely affect performance by forcing Portal to determine group membership repeatedly. Either GroupCache or NestedGroupCache (depending on whether Portal is configured to support nested groups) should generally be enabled to maintain performance.

When changing the PUMA cache values like this one: com.ibm.wps.puma.DN_OID_Cache.size add before the text "cacheinstance.". Otherwise the parameter would not take effect. So the parameter should look like this: cacheinstance.com.ibm.wps.puma.DN_OID_Cache.size
