HP-UX IPFilter Performance White Paper

Outbound TCP (MAERTS) Test Results

The netperf TCP MAERTS test also measures unidirectional transmission of TCP data without

connection establishment time. In a TCP MAERTS test, the netserver server sends streams of TCP

data to the netperf client, so measurements taken on the netserver system indicate performance

for processing outbound packets. IPFilter is installed and configured on the netserver system.

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

system:

• Outbound TCP Throughput

The data transfer rate, expressed in Mb/s.

• Outbound TCP CPU Utilization

The percentage of CPU capacity used.

• Outbound TCP Service Demand

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