When task switching is reported by “Network Packet Received,” the task switch is due to one of these causes:
A task received part of a multipacket batch and was switched out waiting for the client to send the next packet of the batch, or
A task completely finished processing the current batch and was put into a receive sleep state while waiting to receive the next command or packet from the client. This is the most common reason for task context switches due to “Network Packet Received.”
If “Network Packet Received” is high, see “Network I/O Management”. You can configure the network packet size for all connections or allow certain connections, to log in using larger packet sizes.
See Chapter 1, “Introduction to the Basics,” in Performance and Tuning Series: Basics for more information about network packet sizes.
For more information about configuration parameters, see Chapter 5, “Setting Configuration Parameters,” in the System Administration Guide, Volume One.
