Novell GROUPWISE 8 - ADMINISTRATION Administration Manual page 579

By default, the POA is configured to handle a typical amount of purging efficiently. However, if the
default configuration is unacceptably slow during periods of heavy purging, you can prevent users'
client response time from degrading by adjusting the POA's configuration so that it passes pass
additional purge operations to background threads. This leaves the POA's normal client/server
threads available for responding to users' ongoing requests.
1 In the POA Web console, click Configuration > Mass Purge Items Threshold.
The default settings are typically appropriate.
2 (Conditional) If users are experiencing sluggish response time at the beginning of the day,
increase the settings until satisfactory response time is achieved.
Purge Items Threshold: Select the maximum number of items that the POA immediately
purges from a mailbox by using an active client/server thread. The default number of items to
immediately purge is less than 10. Valid values range from 5 to 50.
Max Concurrent Threads Limit: Select the maximum number of background threads that the
POA can start for purging batches of items that exceed the Mass Purge Items Threshold setting.
The default number of background threads for purging items is 3. Valid values range from 1 to
8.
3 Click Submit after changing the setting.
The POA automatically restarts to put the new setting into effect.
