Optimizing the POA

3 8
You can adjust how the POA functions to optimize its performance. Before attempting optimization,
you should run the POA long enough to observe its efficiency and its impact on other network
applications running on the same server. See
Also, remember that optimizing your network hardware and operating system can make a difference
in POA performance.
The following topics help you optimize the POA:

38.1 Optimizing Client/Server Processing

If you run only one POA for the post office, you can adjust the number of POA threads and
connections for client/server processing. If client/server processing needs are extremely heavy for a
post office, you can set up a dedicated client/server POA to meet those needs.

page 561

38.1.1 Adjusting the Number of POA Threads for Client/Server
Processing
If the POA is configured with client/server processing enabled, it starts client/server handler threads
to respond to current client/server requests, up to the number of threads specified by the Client/
Server Handler Threads option. To respond to occasional heavy loads, the POA can increase the
number of client/server handler threads above the specified amount if CPU utilization is below the
threshold established by the CPU Utilization setting. When the POA rereads its configuration
information, the number of client/server handler threads drops back within the configured limit. You
can determine how often this happens by checking the Client/Server Pending Requests History page
at the POA Web console.
If the POA is frequently not keeping up with the client/server requests from GroupWise
users, you can increase the maximum number of client/server handler threads so the POA can create
additional threads as needed. The default is 10 client/server handler threads; valid values range from
1 to 50.
