This field specifies the number of poll threads for a specific protocol. The default value of poll_threads is 1.
If your database server has a large number of connections, you might be able to improve performance by increasing the number of poll threads. In general, each poll thread can handle approximately 200 to 250 connections.
The following example illustrates NETTYPE parameters to increase the number of poll threads and decrease the number of connections per poll thread. This example allows up to 60 connections of a shared memory connection.
NETTYPE ipcshm,3,20,CPU
For more information on monitoring and tuning the number of poll threads and connections, refer to your IBM Informix: Performance Guide.
