At startup, the PingDirectory server logs information about the group membership cache's memory consumption.
The hard-coded cache contains information about the group memberships for internal processing, such as Access control instructions (ACIs). By default, the group membership cache is enabled.
The information about this cache logs to the standard output log server.out and the standard error log. When using groups, use the log information to tune the server for best performance. At startup, the server logs a message to the server.out log.
The following is a sample standard output log.
