      Description

      Elevation of response times, particularly on GWTRPC commands, has occurred as a result of the new permissions model and in particular because of the DatabaseProvider implementation.

      To improve performance across the board, the following actions have been taken:

      • Request caching of DatabaseMeta and DatabaseGrants.
      • Improvement of DatabaseCatalog routine so that UserDatabaseMeta are only requested when needed.
      • Batch requests for DatabaseMeta, DatabaseGrant and UserDatabaseMeta - including requests for FormClasses and versions.
      • Classes which require fetches of a number of UserDatabaseMeta in a request should now batch their requests (e.g. BatchingFormTreeBuilder, FormSupervisorAdapter).
      • The FormSupervisorAdapter now includes a request cache for FormPermissions to avoid duplicate fetches.

      The effect of these performance enhancements will be monitored, and further choke points will be addressed if required.
