HP-UX IPFilter Performance White Paper

Inbound TCP (Streams) Test Results

The netperf TCP Streams test measures unidirectional transmission of TCP data and does not

include connection establishment time. In a TCP Streams test, the netperf client sends streams of

TCP data to the netserver server. Measurements taken on the netserver system indicate

performance for processing inbound packets. IPFilter is installed and configured on the netserver

system.

This document includes the following data from TCP Streams tests, as measured on the netserver

system:

• Inbound TCP Throughput

The data transfer rate, expressed in Mb/s.

• Inbound TCP CPU Utilization

The percentage of CPU capacity used.

• Inbound TCP Service Demand

The number of microseconds of CPU time required to process one KB of inbound data.
