PM96515: REDUCE PERFORMANCE IMPACT WHEN LARGE NUMBER OF LIBRARIES ARE CON FIGURED IN THE AUTHORING PORTLET

APAR status

• Closed as program error.

Error description

• In WCM environments that have many libraries (50+) it is
  possible to configure the WCM Authoring Portlet to allow users
  with the appropriate access to explore all of these available
  libraries.
  
  As the number of libraries available through the
  authoring portlet increases the impact of processing the access
  rights authoring capability increases increasing page rendering
  times.
  
  Typically the security checks and existence checks to
  determine the set of available libraries is cached and causes
  minimal impact to a request, but if the caches are cleared or
  items have yet to be cached then the impact to request
  performance can be noticeable.
  

Local fix

• Reduce the number of available configured libraries within the
  Authoring portlet at any given instance.
  

Problem summary

• In WCM environments that have many libraries (50+) it is
  possible to configure the WCM Authoring Portlet to allow users
  with the appropriate access to explore all of these available
  libraries.
  
  As the number of libraries available through the authoring
  portlet increases the impact of processing the access
  rights authoring capability increases increasing page rendering
  times.
  
  Typically the security checks and existence checks to determine
  the set of available libraries is cached and causes minimal
  impact to a request, but if the caches are cleared or items have
  yet to be cached then the impact to request performance can be
  noticeable.
  

Problem conclusion

• To minimise the impact of configuring an authoring portlet to
  have a large number of available libraries the algorithm
  determining user rights to authoring capability has been
  optimised to reduce unnecessary access checking against all
  available libraries.
  

Temporary fix
