Client/Server Communications
Using the TCP/IP protocol
Increasing the packet size may improve query response time, especially for queries transferring a large amount of data between a client and a server process. You can set the packet size using the -p option in the database server command, or by setting the CommBufferSize (CBSIZE) connection parameter in your connection profile.
For more information, see -p server option, or CommBufferSize connection parameter [CBSIZE].
