Description

Depending on profiling rules, the Page Manager may be asked repeatedly to lookup folders that do not exist. Since these negative hits are not cached, a query to the DB will be used to verify the fact that the folder does not exist each time. This could impact J2 performance for large numbers of concurrent users.
